First of all it's a another tool, and if you are using it correctly, it is
faster and more efficient then using pos, copy and looping across each char
on your own, because the code is very optimized and reduce your work when
parsing for patterns. It is bad practice when you use it for non pattern
usage, or when you know the exact location and length of each sub string you
wish to extract. Otherwise it only makes life more easier imho.

Amm, The metaphor should be learning a new rule in the English language to
use the English language better.
