05:03 PM Ruby Feature #22108: Computed hash keys with (expr): syntax

I am not very in favor of adding yet another hash assoc syntax, especially not by overloading the meaning of the colon. Right now a colon suffix always means a symbol (indeed I've seen static analysis tools that check `slice[-1] == ":"` ... kddnewton (Kevin Newton)

01:47 PM Ruby Revision 1db8b867 (git): [ruby/prism] Fix in handling

in is a unique keyword because it can be the start of a clause or
an infix keyword. We need to be explicitly sure that even though in
_could_ close an expression context (the body of another in clause)
that we are not also parsing an inl... kddnewton (Kevin Newton)

06:59 AM Ruby Revision ab2bc7e9 (git): [ruby/json] Make the JSON parse loop iterative

As opposed to a recursive loop. We do this by keeping a stack of
frames (very similar to how the stack of values was already
stored). Each frame represents the state of a container. Since
there are only 2 in JSON, it doesn't have to get ... kddnewton (Kevin Newton)

Re-opening, we need a syntax error for parse.y. kddnewton (Kevin Newton)

12:37 AM Ruby Feature #21998: Add {Method,UnboundMethod,Proc}#source_range

> It makes no sense for the range of the syntactic block here to include the entire expression of the call and its arguments.
If I'm understanding you correctly, then what you would like for source_range for the example for `foo` and ... kddnewton (Kevin Newton)

12:34 AM Ruby Feature #21795: Methods for retrieving ASTs

Necessarily if the ABI changes, it means the AST shape changed. So how can you possibly expect it to work "whether the loaded prism gem ABI matches that or not". If the AST shape changed, then you're guessing. Unless you're once again su... kddnewton (Kevin Newton)
