Someone wrote it and I am trying to understand that's why.

sub parse_text()

This is the *exact* code that someone wrote? Copy and pasted? Fire
that person. Or at the very least, don't use any more of his/her
code. He/She does't know what he/she's doing.

This code explicitly states that the subroutine does not take any
arguments.... and the very first thing it does is to retrieve the
argument. The only way this code works if the calls to the code use
the &-calling notation, which is evil for other reasons as well.
