Summary:
I have a framework named Set, now partly redundant due to the existence of Set<T> in the stdlib. I’m getting loads of bogus “Cannot specialize a non-generic definition” errors now.


Steps to Reproduce:
1. Make a framework named Set, with a generic type named Set<T> in it.
2. Compile the following code in another module importing Set:

println(Swift.Set<Int>.self)
println(Set.Set<Int>.self)
println(Set<Int>.self)


Expected Results:
I expected it to compile correctly, perhaps griping about the third one because of ambiguity (but ideally not since I’m explicitly importing Set above this).


Actual Results:
/Users/rob/Developer/Projects/Swift/Set/SetTests/SetPrintableTests.swift:11:15: error: cannot specialize a non-generic definition
                println(Set.Set<Int>.self)
                            ^
/Users/rob/Developer/Projects/Swift/Set/SetTests/SetPrintableTests.swift:11:18: note: while parsing this '<' as a type parameter bracket
                println(Set.Set<Int>.self)
                               ^
/Users/rob/Developer/Projects/Swift/Set/SetTests/SetPrintableTests.swift:12:11: error: cannot specialize a non-generic definition
                println(Set<Int>.self)
                        ^
/Users/rob/Developer/Projects/Swift/Set/SetTests/SetPrintableTests.swift:12:14: note: while parsing this '<' as a type parameter bracket
                println(Set<Int>.self)
                           ^


Regression:
My Box framework, containing a generic type Box<T>, does not have this problem when used via its tests.


Notes:
I get the same error with:

println(Set.Multiset<Int>.self)

/Users/rob/Developer/Projects/Swift/Set/SetTests/SetPrintableTests.swift:10:15: error: cannot specialize a non-generic definition
                println(Set.Multiset<Int>.self)
                            ^
/Users/rob/Developer/Projects/Swift/Set/SetTests/SetPrintableTests.swift:10:23: note: while parsing this '<' as a type parameter bracket
                println(Set.Multiset<Int>.self)
                                    ^

So it seems to be having trouble resolving Set correctly.
