Hello
When I say (‘?’) x 3
I get: (‘?’, ‘?’, ‘?’)
I don’t know what happens.
Is this a new syntax for perl
it is very old syntax (i think even back to perl4). the x operator
duplicates the left side by the count on the right side. if the left is
a scalar, the duplicates are merged into a single scalar. if the left
side is in (), it is assumed to be a list and the duplicates are merged
into a list. so what you see is a list of '?' duplicated into the list
you got. you can read more about x in perldoc perlop.
