I usually use re 'debug'; when debugging regular expressions, but I'm not sure it's helpful in this case.

The usual suspects are .* or .*?, because they start by matching the whole string and then backtracking to match less. Can't you replace them with [^;]* or similar?

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
