Status: * [x] parsing code with generics * [x] instantiate generics from concrete types * [x] automatic type inference * [x] support of generic recursive types * [x] support of generic methods * [x] support of generic receivers in methods * [x] support of multiple type parameters * [x] support of generic constraints * [x] tests (see _test/gen*.go) Fixes #1363.
