Can anyone explain what is mean by clustering and capturing?
Or even the difference between them?
I'm reading the docs and came across this.
This is for clustering, not capturing; it groups
subexpressions like "()", but doesn't make backreferences
as "()" does. So
@fields = split(/\b(?:a|b|c)\b/)
@fields = split(/\b(a|b|c)\b/)
