libsub-exporter-formethods-perl

The synopsis section, above, looks almost indistinguishable from any other use of Sub::Exporter, apart from the use of 'method_installer'. It is nearly indistinguishable in behavior, too. The only change is that subroutines exported from Method::Builder into named slots in Vehicle::Autobot will be wrapped in a subroutine called 'Vehicle::Autobot::transform'. This will insert a named frame into stack traces to aid in debugging. More importantly (for the author, anyway), they will not be removed by namespace::autoclean. This makes the following code work: package MyLibrary; use Math::Trig qw(tan); # uses Exporter.pm use String::Truncate qw(trunc); # uses Sub::Exporter's defaults use Sub::Exporter::ForMethods qw(method_installer); use Mixin::Linewise { installer => method_installer }, qw(read_file); use namespace::autoclean; ... 1; After MyLibrary is compiled, 'namespace::autoclean' will remove 'tan' and 'trunc' as foreign contaminants, but will leave 'read_file' in place. It will also remove 'method_installer', an added win.
