Subject: Re: Input: sentence Modify: words Output: modified sentence

Building on what Matthew and tamouse demonstrated (I didn't know about 
the block form before), I've come up with this:

code:
_____

puts gets.chomp.gsub( 
/\b([[:alpha:]'\-&&[^\d]])([[:alpha:]'\-&&[^\d]]{1,})([[:alpha:]'\-&&[^\d]])\b/ 
) { "#{ $1 }#{ $2.length }#{ $3 }" }
_____

input:

"There won't be a cul-de-sac on 2nd St. until April 3, 2015. But, we'll 
be waiting."

output:

"T3e w3t be a c8c on 2nd St. u3l A3l 3, 2015. B1t, w3l be w5g."

We could go on refining this forever with unusual use cases :p
