This complies with the perlcritic policy Subroutines::RequireFinalReturn, which is a severity 4 policy. Since we only currently check at severity level 5, the policy is raised to that level until we move to level 4 or lower, so that any new infringements will be caught. A small cosmetic piece of tidying of the pgperlcritic script is included. Mike Blackwell Discussion: https://postgr.es/m/CAESHdJpfFm_9wQnQ3koY3c91FoRQsO-fh02za9R3OEMndOn84A@mail.gmail.com

# A simple 'tee' implementation, using perl tie.

# Whenever you print to the handle, it gets forwarded to a list of
|
|
# handles. The list of output filehandles is passed to the constructor.
|
|
#
|
|
# This is similar to IO::Tee, but only used for output. Only the PRINT
|
|
# method is currently implemented; that's all we need. We don't want to
|
|
# depend on IO::Tee just for this.
