why waste time duplicating a string?
I just checked and std.conv.to always allocates a copy, even when
constness doesn't require it. It should not reallocate when
constness doesn't change, or is a safe conversion (e.g. immutable
-> const).
A discussion on a related topic (formatting of C strings results
in unexpected behavior) is here:
