Re^3: Hard syntax error or disambiguable parsing?

for $i ( 0 .. 5 ) is not a foreach loop

May I ask you in what way

for $i ( 0 .. 5 )
[download]

and

foreach $i ( 0 .. 5 )
[download]

differ, according to your opinion? perlsyn says The "foreach" keyword is actually a synonym for the "for" keyword, so I don't see how you came to the idea that the for loop your mention, would not be a foreach loop. Did I miss something here?

Did I miss something here? You probably think the "`..`" in "`for[each] $i ( 0 .. 5 )`" is the range operator and that it creates a list of 6 elements. It's not, and no list of 6 elements is created. perlsyn distinguishes between For Loops ("C"-style For Loops) and Foreach Loops (List Iteration Loops), but "`for[each] $i ( 0 .. 5 )`" is neither. It's actually a Counting Loop like `FOR ... NEXT` in BASIC.	[reply] [d/l] [select]
