Modified: docs/Perl6/Spec/S06-routines.pod Log: [S06] make MAIN short switches a bit saner The variable name of a parameter is purely an implementation detail of the subroutine, and shouldn't be a concern while parsing command line arguments. Instead rely on already existing alias syntax for named parameters.

To give both a long and a short switch name, you may use the pair -notation. The key will be considered the short switch name, while -the variable name will be considered the long switch name. So if -the previous declaration had been: +notation to install several names for the same parameter. +If any of the names is a single character, it will be considered a +short switch name, while all other parameters names are considered +as long switch name. So if the previous declaration had been: - sub MAIN (:f($frompart), :t($topart), *...@rest) + sub MAIN (:f(:$frompart), :t(:$topart), *...@rest) then you could invoke the program with either C<-f> or C<--frompart> to specify the first parameter. Likewise you could use either C<-t>
