Re: Sorting result of function call
in thread Sorting result of function call
Thanks for trying that out. Deparse is a good idea, I get the same results as you except for case two, where my Deparse says
say sort('get_keys' ());
say((sort get_keys ()));
Interestingly, feeding my Deparse output back to perl leads to a syntax error. Your version seems to indicate what perl is doing here. Trying to sort the empty list () with the compare-function get_keys, hence the empty return.
