I think this is a simple question. But somehow not working for me.

Can we use an array element as a loop iterator for another array?

Here is the code which fails(Ignoring all strict and other things).

perl -e '@a=(1,2,3);@b=(2,4,6,7);foreach $a[1](@b){print $a[1];}'

Error: syntax error at -e line 1, near "$a["

I have checked. This works with a c-style for loop.

for($a[1]=0;$a[1]<3;$a[1]++){print $b[$a[1]];}

Similar thing works in python. What is the mistake in this due to which it is failing. Would be thankful for your help
