=item code generation

a number of the syntactic shortcuts that FAST::List::Gen provides will construct and
then evaluate code behind the scenes.  Normally this is transparent, but if you
are trying to debug a problem, hidden code is never a good thing.  You can
lexically enable the printing of evaled code with:

    local $FAST::List::Gen::SAY_EVAL = 1;

    my $fib = <0, 1, *+*...>;

    #   eval: ' @pre = (0, 1)' at (file.pl) line ##
    #   eval: 'FAST::List::Gen::iterate { if (@pre) {shift @pre}
    #            else { $fetch->(undef, $_ - 2) + $fetch->(undef, $_ - 1) }
