Request: short circuit evaluation #434

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. if GetVirtualButtonExists(1) and GetVirtualButtonPressed(1) then..
2.
3.

What is the expected output? What do you see instead?

all are evaluated and of course if not exists, then get error

What version of the product are you using? On what operating system?

108

Please provide any additional information below.

In any boolean comparision, shortcircuit the result when it is already known 
(e.g. first condition fails, don't bother testing the rest)

I am not sure why should it test the rest of conditions, while you use -and- 
operator there. Could your describe your problem further?

Kamac, you have misread the issue report.

I quote:
"In any boolean comparision, shortcircuit the result when it is already known.
[In case of the AND operator, if the] first condition fails, don't bother 
testing the rest."

Currently - AGK doesn't use shortcircuit evaluation. But it should...

Cheers.
