Bug #20062
closedNumbered parameters are broken in Ruby 3.3-dev
Description
Define Numbered parameters and a method in one block and then reference Numbered parameters in another block, you will get a SyntaxError in Ruby 3.3.
This is not a problem in Ruby 3.2.
'a'.tap do
p _1
def f1; end
end
'a'.tap do
p _1
end
__END__
output:
Ruby 3.2.2 =>
"a"
"a"
Ruby 3.3.0dev(2023-12-13T13:16:11Z master f390c51b15) =>
/path/to/test.rb:
/path/to/test.rb:8: numbered parameter is already used in (SyntaxError)
/path/to/test.rb:2: outer block here
I noticed this while checking the operation of https://bugs.ruby-lang.org/issues/18966.
I haven't checked, but https://bugs.ruby-lang.org/issues/19619 may be related.

It indeed seems to have been broken since https://github.com/ruby/ruby/pull/7779.

[Bug #20062] Fixed numbered parameter syntax error
At the method definition, the local scope that saves the context of
the numbered parameters needs to be pushed before saving.

I believe this issue is not the case on ruby_3_2. The test case added was passed with current ruby_3_2 branch.
