My goal:
store a pattern in a variable for future use

My problem:
if the pattern I stored has a pattern name in it, (like i_/;i=8),
and I use it later to build a new pattern in which I use the stored pattern twice, it thinks its the same name (i)

My investigation:
So far, couldn't find any way to scope pattern's names in a useful way.
Module and With, refuse to scope a pattern name that's somewhere on the left hand side of a condition contained in them.

Sure, I probably haven't tried much yet to build what I want with hard expression manipulation, but... I found my objective neat simple and useful...
I would like to know if there's a proper way to do this, or to achieve my objective somehow else. And, I'd also enjoy knowing why such a resistance to scope pattern names...
