Re^2: How to distinct the call position of a sub?

Well ... would you publish a syntax extension with the footnote "but never use it in the same line!" ?

And beside this, iterator are just an example for a general problem to know "which call is this".

Think about a position sensitive function you want to call twice within a ternary operator ... "never use it in the same line?"

And even when I publish it with this restriction, I have no means to throw an error-message if used in a wrong way.

So if there is a general clean solution, where else should I try to ask for wisdom?
And shouldn't I ask before implementing an imperfect solution? 8 )

> What do you expect to get if you're called from string eval? what do you expect when you call foreach from string eval? Well you bring a good argument against using the linenumber from caller. Cheers Rolf	[reply]
