+Description: Perl module for subroutine signatures with no source filter
+ With signatures, you can specify subroutine signatures and have
+ variables automatically defined within the subroutine. Note that,
+ although the syntax is very similar, the signatures provided by this
+ module are not to be confused with the prototypes described in
+ perlsub. All this module does is extracting items of @_ and assigning
+ them to the variables in the parameter list. No argument validation
+ is done at runtime.
