Apropos that: when I looked at gnat's regexp package I saw a comment
about certain functions being evaluated twice, once to determine the
size and another time to actually produce the results. Have I
understood correctly that in for instance
s : String := function_returning_a_string_of_variable_length(junk :
Integer);
the function is actually evaluated twice? (Stupid question of me to
ask, really, but I don't have an Ada compiler at school). Would it do
that in java too?
