In working with Range a while back, I was frustrated to find that writing a subclass that wanted to override an accessor (e.g. for $.min and $.max) was quite difficult because most methods ignored the accessors and called $!min and $!max or wrote to them directly. If I really wanted to change the semantics, I pretty much had to re-write or at least wrap every existing method, which would make my module nigh unmaintainable.
Is this for performance reasons? Would it make sense to try to find a way to make this easier? As a concrete example, here's how "elems" is defined on Range: https://github.com/rakudo/rakudo/blob/32902f25ca753860067a34eb9741aa5524dbe64e/src/core/Range.pm#L96 -- Aaron Sherman, M.: P: 617-440-4332 Google Talk, Email and Google Plus: a...@ajs.com Toolsmith, developer, gamer and life-long student.
