This is in some function:
emitsignal("variablechanged", name)

Then, elsewhere, I want to do something like this:
yield(getnode("."), "variablechanged(my_variable)")

I want to yield when that signal is emitted, but only when "my_variable" is passed into the signal. How can I do this?

You could yield in a loop like

while yield(getnode("."), "variablechanged") != "my_variable":

Better version suggested by Zylann:

while yield(self, "variablechanged") != "my_variable":

get_node(".") is a useless call, you can use self directly

Right, sorry.
