It whould be very nice see something similar to .function from your
example in bmake but I don't beleive it will appear in nearest future.
1) .function is much harder to implement than yesno/istrue/whatever in C
2) if/when .function is implemented, yesno written in C can easily be
replaced with code from your example, implemneted in, for example,
bmake_builtins.mk which is always read on bmake startup.
3) Stable API, widely used yesno/istrue function, is more important than
