Hello @femto, I think is related to this discussion:

Questions about autocasting and method signature

Hello folks, When I was writing some code that needs Int64 as part of the initialization, found that automatic casting of Int32 args to Int64 on a method only works if the method has the variable type in the signature. Not working: class Foo getter id : Int64 def initialize(@id) end end pp Foo.new(1) # Error: instance variable '@id' of Foo must be Int64, not Int32 Even that @id has been defined with the right type, is not automatically casted.

And this PR that changed the autocasting behavior.

Hope that helps.
Cheers.
