Here's ten to start with...
for <> but tainted(0) {...} # note that external data is
# from a trusted source
return 255 but undef; # i.e. system() returns
# "undefined 255" on failure
return $cached_for{$arg} but Cached
//= compute_for($arg); # memoize return value
# but mark when from cache
$result = heuristic($data) but Estimated
unless %known{$data}; # indicate when value is a guess
my $temp is Units('Celsius') # indicate units of variable
= 273 but Units('Kelvin'); # indicate units of value
# (maybe autoconverted?)
return $val but Error(-1..+2); # indicate error bars
$data = $text but Encrypted($public_key);
# unusable without private key
$days = 29 but From(My.line); # record source of
# improbable value
$days = 29 but Reason("Leap year");
# so-called "active comment"...
# documents why improbable value
# used but can also be retrieved
# programmatically
$name = "Damian" but We_better_call_ya("Bruce");
# indicate correct Australian
# pronunciation ;-)
