Bug 13056 – [2.066.0-b1] Regression: Error: template std.path.baseName cannot deduce function from argument types !()(DirEntry)

The following compiles on DMD 2.065.0 but not in 2.066.0-b1: regress.d: ````d import std.file; import std.path; import std.string; import std.stdio; void main() { foreach(de; dirEntries(".", SpanMode.depth)) { writeln(de.baseName); } } ```` Output: regress.d(10): Error: template std.path.baseName cannot deduce function from argument types !()(DirEntry), candidates are: /usr/share/dmd/src/phobos/std/path.d(287): std.path.baseName(R)(R path) if (isRandomAccessRange!R && hasSlicing!R && isSomeChar!(ElementType!R) || isSomeString!R) /usr/share/dmd/src/phobos/std/path.d(311): std.path.baseName(CaseSensitive cs = CaseSensitive.osDefault, C, C1)(inout(C)[] path, in C1[] suffix) if (isSomeChar!C && isSomeChar!C1)

A reduced test case: import std.range; struct DirEntry { alias name this; @property string name(); } void main() { static assert(isRandomAccessRange!DirEntry); }

This boils down to, once again, front() returning a different type than the indexed type for narrow strings. Arggh.
