When you know a better way. That replacements could be functions had
escaped my attention; your solution is clearly better. No
measurements needed to realise that.
And both solutions may or may not be better that the OPs original
one-sub-at-a-time approach. I'll leave it to the OP to find that out.
After all, the OP can do the testing with the right regexps on the
right data. Synthetic benchmarks give synthetic results.
