with p5, Ive often written
eval {} or carp "$@ blah";
it seems to work, and it reads nicer (to my eye) than
eval {}; if ($@) {}
but I surmise that it works cuz the return-value from the block is non-zero,
for successful eval, and 0 or undef when block dies, not cuz of magical
treatment of $@.
I gather that ';' is unneeded in p6, and given that $! is the
'exception'al topicalizer,
is this construct no longer reliant on the last value in the eval block ?
put another way, does the 'topicalizer' reflect the exit condition of
the closure ?
