Subject: what is best idiom to remove file extension

What is the most concise, bulletproof idiom for removing the file
extension from a file?  Maybe I've missed something obvious that
everyone else uses...

Here's what I usually do:

This is what I usually use if I want bulletproof:
  filename.sub(/#{Regexp.escape(File.extname(filename))}$/, '')

I use something like this when I want something quick:
  filename.sub(/\.\w$/,'')

One could imagine doing something like this, but it is comical how
much code it takes:
  File.join( File.dirname(filename), File.basename(filename,
File.extname(filename)))

What do you use for this (seemingly) trivial task?

Thanks,
John
