So you have a string which contains a Go type expression, and you want to find out attributes of that type? In general you can't do that without knowing the context that the expression is to be evaluated in. For example, the string "T" could be any kind of type if T is defined as a type somewhere.
Assuming you know the package that the type expression is in, you could use https://godoc.org/golang.org/x/tools/go/packages to load it up, then use https://golang.org/pkg/go/ast to parse the type expression and use the results of the first to look up symbols from the resulting AST. cheers, rog.
