Even C can give you fat executables. What with loop unrolling and the 
strange instruction scheduling that
the optimizer generates for modern processors. The compiler I use goes 
out of it's way to avoid branches. Sometimes
a small loop can be unrolled into a hundred instructions using 
load-on-condition/store-on-condition instructions. A memcpy()
when the length is constant can generate 20-30 move instructions. It's a 
space for time trade-off.
