This is an enhancement request, but it's borderline being a bug report for the module system.

Two similar examples:


void main() {
    int map;
    import std.algorithm;
    map!(x => x)([1]);
}



void main() {
    int map;
    import std.algorithm: map;
    map!(x => x)([1]);
}


In both cases dmd 2.066alpha gives:

test.d(4,8): Error: no property 'map' for type 'int[]'
test.d(5,5): Error: template instance map!((x) => x) map is not a template declaration, it is a variable


In both programs I expect something like a "'map' identifier shadowing error".

An explicit "import std.algorithm: map;" getting totally ignored is not acceptable, in my opinion.
