in reply to function call / return philosophies

Varying return types has always caused problem for me down the road. Best thing to do might be to always return ref regardless of the number of parameters you receive.

I think a hashref here is a better return value than an array ref. Perl already has hashes built in. If you return an array ref, you are forcing the user of your API to re-implement associative arrays.

[jdporter]: currently it expects the bitmask to be in the form of a hex number, e.g. 0x0101
[jdporter]: but I'd like to let the user specify it as individual bits, i.e. 0b0000000100000001
[jdporter]: there is no bit/binary equivalent of hex, right?
[jdporter]: I guess that the most direct way of doing it is with some magical incantation involving unpack or whatever
[jdporter]: let me google that for me ;-)
[jdporter]: hex points explicitly to oct, which does the job. :-D
[jdporter]: omg, I f love Perl!
[choroba]: say unpack 'H*', pack 'B*', $mask =~ /0b([01]+)/;
