in reply to Re^2: What is $x{$y}?in thread What is $x{$y}?
For instance, in a foreach $x(@y){} line of code.
How about $x{@y} then? How does that work ... in a foreach $x(@y){} line of code.
There is no $x{@y} expression in the foreach $x(@y){} statement. In that statement, $x is aliased to successive elements of the @y array on each execution of the loop.
