Hello
Take this file...
I want to substitute every occurrence of Test[0-9]{2} with a unique random number, so for example, if I was using sed, substitution would be something like the below but obviously the below does reevaluate the random number for each occurrence of Test[0-9]{2}
So on the execution of substitution, the file would read something like

Cache::Ref::CLOCK(3pm) User Contributed Perl Documentation Cache::Ref::CLOCK(3pm)NAME
Cache::Ref::CLOCK - CLOCK cache replacement algorithm
SYNOPSIS
my $c = Cache::Ref::CLOCK->new(
size => $n,
k => $k,
);
DESCRIPTION
This algorithm is provides a second chance FIFO cache expiry policy using a circular buffer.
It is a very well accepted page replacement algorithm, but largely for reasons which are irrelevant in this context (cache hits don't need
to be serialized in a multiprocessing context as they only require an idempotent operation (setting a bit to 1)).
ATTRIBUTES
size
The size of the live entries.
k This is the initial value given to all hit entries.
As the hand moves through the circular buffer it decrements the counters.
The default is 1, providing semantics similar to a second chance FIFO cache.
Larger values of "k" model LRU more accurately.
This is pretty silly though, as Cache::Ref::LRU is probably way more efficient for any "k" bigger than 1.
