|Summary||0007524: Add warning when using '=' in for none immediate values|
|Description||This is a proposal/request for creating a warning that will be trigger when using '=' on any value that is not immediate (like lists, records).|
The main motivation is to avoid problems as the ones described in the reports 0003921, 0007502.
We were also affected in our product by this behavior. The problem that we had was that an algorithm using 'compare a b = 0' was changed to 'a = b'. This produced a big performance degradation since we were not aware that '=' didn't performed physical comparison.
When enabling this warning new programmers will be notified of this behavior therefore avoiding the unintended consequence.
|Tags||No tags attached.|
|It's hard at the moment to imagine our being able to turn this warning on by default, I think, so the benefit to new users may be harder to achieve. That doesn't detract from the benefit of having the warning, though.|
