_D3std6format__T11hasToStringTSQBd8datetime7systime7SysTimeTaZ9__lambda2MFZ1S3putMFNaNbNiNfaZv

... demangles to...

pure nothrow @nogc @safe void
std.format.hasToString!(std.datetime.systime.SysTime,
char).__lambda2().S.put(char)

When logging semantic in the compiler, I don't see it in the AST either.
