You can make b
an alias for a
with *b = *a
. This means that $a
and $b
refer to the same variable, as do @a
and @b
, and even filehandles and formats a
and b
. You can also localize *b
inside a block with local(*b)
, and that lets you have local filehandles and formats and other things. Pretty fancy stuff, but useful when you need it.
