I am "trying" to write a function that takes an array of items,
and returns the length of longest item.
[code]
size_t maxLength(A)( const A[] listOfString ) if( __traits(
hasMember, A, "length" ) )
{
return 0; // not implemented yet
}
[/code]
I tried it with
if( __traits( compiles,

I'm 99% sure something like __traits(hasMember, int[], "length"
) should evaluate to true. Please file a bug at
issues.dlang.org I notice it also doesn't work for
