Symbol-Array loop and `define_method` finds only one method.

[ellcs]

Hello! The last time i tried define_method typeprof couldn't handle it at all. I am happy that it changed and it is nice to see the progress.

Issue

As you can see i provide an array of method names, iterate over them and create an empty method.
My expectation would be that the class Human would have two methods in the typeprof output: :a and :b. But only :a is shown.

I am quite sure this is a hard bug, because it relies on loop unwrapping.

ruby

class Human
  define_method(:fo) { }
  
  [:a, :b].each { |m|
    define_method(m) { }
  }
end

rbs

output

# TypeProf 0.12.0

# Classes
class Human
  def a: -> nil
end


## Version info:
##   * Ruby: 3.0.0
##   * RBS: 1.0.3
##   * TypeProf: 0.12.0

Try it on playground:

Thank you for your report! TypeProf analyzed the code correctly, but the output of b was unintentionally filtered out. Now TypeProf (in master) produces the following result.

# TypeProf 0.12.0

# Classes
class Human
  def fo: -> nil
  def a: -> nil
  def b: -> nil
end
