BUT - a very big but - the most important issue is the
formatting thing. Even there is no direct dependency on
std.format or std.stdio, the formatting mechanism is designed
to fit nicely into phobos formatting paradigm. That means that
there is no way to output decimal values on the console without
phobos. I confess that 30% of my development time was the
formatting feature: displaying correctly any possible
combination of width, padding, alignment in 4 different formats
(%f, %g, %e, %a) was really a challenge and despite of hundreds
of unit tests, I'm not convinced today that I covered all the
corner cases. The f*cking %g took me 3 days to find out exactly
what is meant to do. More than that, each compiler producer
have a different idea about format specifiers. Linking your
application against snn, msvcrt or glibc will render completely
different results for printf("%g", ...). On top of that,
neither the FormatSpec documentation from phobos is something
complete and clear...
Ilya has expressed interest in a betterC formatting library for
libmir.
