Hi Mitchell,
I'm puzzled by the simplicity of your question.  Does it tell the whole 
story?  If so, you could simplify the whole thing down to:

a, b = input.scan(/\w+/)   # find the two words - there are always two 
words, right?
output = "#{a} } #{b}"         # output the two words with a space brace 
space in the middle


Or maybe it is always just like you show it, and all you want to do is 
remove the '\\' and the outer braces and spaces, in which case it is as 
simple as:

output = input[2..-3].gsub!(%r{\\},'')

Just trying to suggest that with a pattern matching question one needs a 
bit more context in order to know how simple or complicated the matching 
needs to be.  But then, maybe if you told us you would have to shoot us. 
:)

best,
jp
