Ah yeah, sure...
And also my all time favorite staged functions could be misused:
stagedfunction test5()
quote
a = $(a = rand() )
a + a
end
end
But I'm actually searching for answers, why it is like this and what speaks
against a nice solution for such a common use case.
My code using this is absolutely not performance critical ;)
@Mauro I am aware of the scope, and I agree with you. I didn't open an
issue, as I wanted to discuss this first.
