Funny you should bring up this subject, as it was recently rehashed (more like re-re-re-re-hashed!) on perlmonks.org in this discussion thread:
http://perlmonks.org/?node_id=481652 The conclusion of the discussion(s) is that there are valid reasons to use single and double quotes in various circumstances, and that the CPU difference due to possible variable interpolation is minor compared to other considerations. If performance is a problem for your app, your time would be better spent profiling your code and address real issues before addressing the non-issue of variable interpolation.
