How does ruby parse/detect self.name= methods?

Ruby

Hello.

I am a bit confused.

With this class:

class A
def go=(something)
p ‘in go=’
end

def test_go
go=3
end
end

A.new.test_go # does not call go=
A.new.go=3 # does call go=

But it seems like I never run into this problem…so…how does Ruby
ever call a local :method= type method, since they’re always
ambiguous? Or are they?
Thanks!

`go=3’ is always a local variable assignment. No way to prevent
that. What you can do is to tell Ruby the receiver:

def test_go
self.go=3
end

This forces Ruby to look up the #go= method on self directly,
bypassing the local variable guess.
