this is just a prototype here, but in real world these are different scripts which are running. How feasible is it to be defined as a function ?

ppi::token::prototype5.18
PPI::Token::Prototype(3) User Contributed Perl Documentation PPI::Token::Prototype(3)
NAME
PPI::Token::Prototype - A subroutine prototype descriptor
INHERITANCE
PPI::Token::End
isa PPI::Token
isa PPI::Element
SYNOPSIS
sub ($@) prototype;
DESCRIPTION
Although it sort of looks like a list or condition, a subroutine prototype is a lot more like a string. Its job is to provide hints to the
perl compiler on what type of arguments a particular subroutine expects, which the compiler uses to validate parameters at compile-time,
and allows programmers to use the functions without explicit parameter braces.
Due to the rise of OO Perl coding, which ignores these prototypes, they are most often used to allow for constant-like things, and to
"extend" the language and create things that act like keywords and core functions.
# Create something that acts like a constant
sub MYCONSTANT () { 10 }
# Create the "any" core-looking function
sub any (&@) { ... }
if ( any { $_->cute } @babies ) {
...
}
METHODS
This class provides one additional method beyond those defined by the PPI::Token and PPI::Element parent classes.
prototype
The "prototype" accessor returns the actual prototype pattern, stripped of braces and any whitespace inside the pattern.
SUPPORT
See the support section in the main module.
