          Issue ID: 18406
           Summary: __traits( getOverloads ) doesn't accept module symbols
                    as its aggregate parameter
           Product: D

Code example

From the documentation, "The first argument is an aggregate (e.g.

struct/class/module)."

This gets further complicated when doing an allMembers pass of a module with an
overloaded function - the function symbol will show up multiple times, but
since you cannot get the overloads you can only resolve the first overload
encountered by the compiler.

Code example attached. Uses __traits( parent ) to get the module symbol. Other
methods of obtaining the symbol, such as mixing in the name and assigning to an
alias, result in the exact same error.

Expected result: NumOverloads gets the value 2 assigned to it
Actual result: Error message: expression expected as second argument of
__traits getOverloads
