1- isa/can validation in XS allows this: 2 3 { a => { isa => \%hash } } 4 5and tries to see if a->isa("HASH(0x1581)"). Instead, we should die if 6given a non-array reference. Same for can, etc. See how this is 7handled in callbacks for example. 8 9 10- make it possible to explicitly not use the XS version in a non-hacky 11way. 12 13 14- is there something better than "N/A" that could be used when 15validation is being done outside a sub? 16 17 18- add an excludes param to the spec as the opposite of depends, 19suggested by Diab Jerius (see rt.cpan.org). 20
