+## Versioning
 
 Go OLE uses [semantic versioning](http://semver.org) for version numbers, which is similar to the version contract of the Go language. Which means that the major version will always maintain backwards compatibility with minor versions. Minor versions will only add new additions and changes. Fixes will always be in patch. 
 
 This contract should allow you to upgrade to new minor and patch versions without breakage or modifications to your existing code. Leave a ticket, if there is breakage, so that it could be fixed.

+//
+// As of Go 1.11 there is no direct way to know the compile time GOPATH or
+// module paths at runtime, but we can piece together the desired information
+// from available information. We note that runtime.Frame.Function contains the
+// function name qualified by the package path, which includes the module path
+// but not the GOPATH. We can extract the package path from that and append the
+// last segments of the file path to arrive at the desired package qualified
+// file path. For example, given:
+//
+//    GOPATH          /home/user
+//    import path     pkg/sub
+//    frame.File      /home/user/src/pkg/sub/file.go
+//    frame.Function  pkg/sub.Type.Method
+//    Desired return  pkg/sub/file.go
+//
+// It appears that we simply need to trim ".Type.Method" from frame.Function and
+// append "/" + path.Base(file).
+//
+// But there are other wrinkles. Although it is idiomatic to do so, the internal
+// name of a package is not required to match the last segment of its import
+// path. In addition, the introduction of modules in Go 1.11 allows working
+// without a GOPATH. So we also must make these work right:
+//
+//    GOPATH          /home/user
+//    import path     pkg/go-sub
+//    package name    sub
+//    frame.File      /home/user/src/pkg/go-sub/file.go
+//    frame.Function  pkg/sub.Type.Method
+//    Desired return  pkg/go-sub/file.go

+//    frame.Function  pkg/v2/sub.Type.Method
+//    Desired return  pkg/v2/go-sub/file.go
+//
+// We can handle all of these situations by using the package path extracted
+// from frame.Function up to, but not including, the last segment as the prefix

 Every `*<num>` represents the memory address of a handler function (a pointer). If you follow a path trough the tree from the root to the leaf, you get the complete route path, e.g `\blog\:post\`, where `:post` is just a placeholder ([*parameter*](#named-parameters)) for an actual post name. Unlike hash-maps, a tree structure also allows us to use dynamic parts like the `:post` parameter, since we actually match against the routing patterns instead of just comparing hashes. [As benchmarks show](https://github.com/julienschmidt/go-http-routing-benchmark), this works very well and efficient.
 
-Since URL paths have a hierarchical structure and make use only of a limited set of characters (byte values), it is very likely that there are a lot of common prefixes. This allows us to easily reduce the routing into ever smaller problems. Moreover the router manages a separate tree for every request method. For one thing it is more space efficient than holding a method->handle map in every single node, for another thing is also allows us to greatly reduce the routing problem before even starting the look-up in the prefix-tree.
