D - [BUG] nested overload fails

reply larry cowan <larry_member pathlink.com> writes:
Shouldn't this nested overloaded function compile and work?

void main ()
{
void Test ( int i ) { printf("i=%d\n",i); }
void Test ( int i, int j ) { printf("i=%d, j=%d\n"); }
// over.d(4): declaration main.Test is already defined
Test(1);
Test(2,3);
}

use for this here (generally) anyhow as your not going to get much reuse of overloads in nested scope and overloads like this are about reuse. -- -Anderson: http://badmama.com.au/~anderson/

Just trying to get the same convenience I would have had with #defines in C/C++. No big thing, but I don't see why it should work at global scope, but not when nested in a function. In C, I use local #defines to make repetitive code clearer to read, it's useful. /* ****************************************** * * main() - used for testing only * * ****************************************** */ debug (Wildmatch) { void main ( char[][] args ) { version (win32) bit igncase = true; version (linux) bit igncase = false; assert(igncase); if (args.length != 2 && args.length != 3) { printf("Usage: filename [pattern]\n"); return; } char[] fn = args[1]; void TESTPATTERN ( int n, char[] patrn ) { WildMatch wc = new WildMatch(patrn); printf("wc%d%s1(%.*s) is %.*s\n" ,n ,igncase ? "ci" : "cs" ,wc.w() ,wc.test(fn) ? "true" : "false"); } void TESTpattern ( int n, char[] patrn, bit caseins ) { WildMatch wc = new WildMatch(patrn,caseins); printf("wc%d%s1(%.*s) is %.*s\n" ,n ,caseins ? "ci" : "cs" ,wc.w() ,wc.test(fn) ? "true" : "false"); } if (args.length == 3) { TESTPATTERN(0,args[2]); return; } TESTpattern(1,"wildmatch.d",true); // force 1 case-sensitive test TESTpattern(2,"WILDMATCH.d",false); // force 2 case-sensitive tests WildMatch[] wc = { new Wildmatch(3,"*match.d?",false) ,new WildMatch(4,"*") }; printf("wc%d%s1(%.*s) is %.*s\n",3,"cs" ,wc[0].w(),wc[0].test(fn) ?
