timotimo: re "wait, were we going for a "only PRs get to go into master" thing just recently?"

07:16

no, I don't think there was an official decision, it's just that I decided that *I* will not commit anything directly to master anymore

Streamline X::Multi::Ambiguous listing

  - remove ":", it does not convey any information, clear it's a signature
  - add two spaces to set it off the first line
  - add "is default" status of the candidate when applicable

rakudo: b8121cecb9 | (Elizabeth Mattijsen)++ | src/core.c/Exception.pm6
Lose the return constraint

It is not significant in dispatch, so should not be shown on a dispatch error.

Introducing the allomorph class

  - a subclass of Str
  - IntStr/NumStr/RatStr/ComplexStr are now subclasses of allomorph
  - replaced several nqp::ifs by ternaries
  - streamlined many coercions, specifically RatStr.Numeric
  - simplified 16 infix:<eqv> candidates into a single one

ok, looks like there's a cycle in reify-at-least that's causing the 740k calls. AT_POS_SLOW calls reify-at-least 702 times. then reify-at-least (List:40) -> push-at-least (Iterator:49) -> push-exactly (Iterator:28 and Rakudo/Iterator:2028) -> pull-one (List:611) -> reify-at-least (List:40)

09:44

MasterDuke: I think you'll find them to be called on different objects

09:48

MasterDuke

could be, but there doesn't need to be 740k calls in total

09:50

or you mean something is getting cloned that shouldn't?
