           Summary: Two wrong lookups for array functions
           Product: D
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: andrei@metalanguage.com


size_t blah(int[] r) { return r.length; }

struct A
{
    int[] r;
    size_t blah() { return r.blah(); }
}

void main()
{
    A a;
    a.blah;
}

The code above says:

function test.A.blah () does not match parameter types (int[])
Error: expected 0 arguments, not 1

So it looks like the compiler first morphs r.blah() into blah(r), but then uses
the local scope to look for blah. Therefore A.blah will be found, leading to
the nonsensical call this.blah(r).

Interestingly, if the parens are removed leaving r.blah, the lookup is still wrong but in a different way:

Error: no property 'blah' for type 'int[]'

So this time the call fails to start with. Both errors are bugs. The code should compile with and without parentheses.

This is an enhancement. Rewriting:
   array.foo
as:
   .foo(array)
rather than:
   foo(array)
does the trick.

Nah. The whole point was to have obj.foo work for arrays and other beasts.
