What is the rationale for using '=' instead of ':='?

Using '=' evaluates the assignemnt every time it is referenced, which can
be a little bit costly when there are tons of them (like in buildroot);
while using ':=' does the evaluation only once, at the time of the
assignment, not evaluation.

I agree that the code should be homogeneous, but I'd think it should be
fast as well. He, if I can get butter, buter's money, and a litle smile
from the dairywoman! ;-)

Yann E. MORIN.
