           Summary: Alias and function names fail to collide
           Product: D
           Version: 0.156
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: shro8822@uidaho.edu


When a function and an alias have the same name, DMD fails to produce an error unless the function is used directly. Taking the address off the name give no error.

In the following test case the function (not the alias) is arbitrarily picked, however it is also the first definition and if this follows the pattern set in bug #52, reversing the order of the definitions will change this (not checked).

Test case:
-------------
void fn(){assert(0);}   // make a function

void gm(){assert(0);}   // make another function

alias gm fn;            // alias the second with the name of the first

void main()
{                       // make pointer-to-function from name
        void function() fnp = & fn;
                        // call pointer-to-function
        fnp();

        // fn();        // wont compile with this line included
}
-------------
