Did the forum web interface cut off your post? I only see the definition
of Info and nothing else.

Anyway, what I have in mind is more to take the current Phobos
std.format (of which writeln is just a thin wrapper), stick @nogc on it,
and hack it until it either compiles with @nogc, or isolate the GC parts
such that most calls to std.format (via writeln) are @nogc except when
you actually pass it something that must allocate.
