Why is it that much important for this particular library not to resort to
the internal default string allocation.
Whatever it is, is preventing the simpler interface:

std:.string demangle_type(char const* input);

which IMO is a lot much user-friendly.

If I will be forced to explicitly create string objects to use as
placeholders for the result, I would like to have a compelling reason.
