the returned value of Function() is the name of the variable. |

It doesn't matter what is returned, Function() is not a variable name.

i think it still should be changed as it is inconsistent.
| Code: | Loop, % Function()
MsgBox, %A_Index%
Return
Function()
{
Return, 3
} |
works |

I was ready to start a topic, but as I can see, there's allready a topic existing.
I'd also be happy, if it'd be possible to use a function or even a literal string in the parse-loop, like a for-loop using in batch.
Because (from my point of view) it would be more failsafe (one variable less) and I like code that doesn't function right, it should also look nice. (call me a geek  )
Long story short: I'd be pleased if this would be changed.
Thanks

It is not inconsistent.
As described in the help, Loop takes the value from a variable reference (like %Var%), not from a variable (like Var). Overtaking this term, % Function() is a variable reference. |

No this is not a variable reference. The percent sign just puts it into an expression. |

What is the the correct word for %Var%? Traditional and variable reference are often used in the documentation.

You'll agree that in AutoHotkey %Var% is the same as % Var. From the help for MsgBox: | Quote: | | This parameter will not be recognized if it contains an expression or a variable reference such as %option%. |
Possibly you refer to a comment in the example given in that chapter: | Quote: | | By preceding any parameter with "% ", it becomes an expression. |
Maybe this is an unfortunate formulation. "% " followed by an expression is a traditional style parameter.
I think this construction was originally most notably intended to easily identify placeholders for string replacement in a text, as you can see it in the options dialogs of many programs. In the sense of write-as-you-speak:
| Code: | MsgBox Hello %Name%, how are you?
; is more comfortable than
MsgBox("Hello " Name ", how are you?") |
