I keep reading the topic title as "In Defence of Magic" instead of "In Defence of Magic Numbers".

Vaguely related:

The other day; I imagined a pseudo type syntax, similar to the following, which could be used to force a Local copy of a global variable passed as a parameter. It offers no additional, or practical, advantage other than being easy to follow (IMO).

;

Pseudo Code

Global Const $gvVar = True

_Anything($gvVar)

Func _Anything(Not ByRef $gvVar)
    $gvVar = False
EndFunc

;

Although I think 'Not ByRef' is perhaps a bad combination / expression for different reasons. It was merely a passing thought.


Something I think would be very useful would be to have optional ByRef parameters (for passing around large amounts of data - or not), but perhaps there's enough going on right now. Maybe sometime in the future.

All variables are passed 'not byref' by default. Normally byref and byval parameters are distinguished by function overloads but AutoIt doesn't support that right now. You can always have _AnythingV and _AnythingR where the V and R are for value and reference respectively.

I appreciate all the effort made by MVPs to name all constants. The fact I find using them laborious is just too bad. I think Microsoft's naming policy is simply inane. I like working with numbers. I find it easier to track bugs and understand the inner workings. I don't really like to have things hidden behind a veil. It's my personal preferance. I have the option to use global constants if I wish to and quite often I do.
