Maybe more interesting than reading 'regex' itself is how to you read an actual regex? For example:

$_ !~ /^((\d+\!)*\d+([\,\-]\d+)*:\d+([\,\-]\d+)*(\;)?)+$/

Is that "dollar sign underscore space exclamation point tilde space forward slash caret open parenthesis ..."

Or do you abbreviate: "dollar underscore bang twiddle slash hat paren ..."
