# Perl::Critic::Policy::Subroutines::ProhibitAmpersandSigils(3pm)

Don't call functions with a leading ampersand sigil.

## NAME

Perl::Critic::Policy::Subroutines::ProhibitAmpersandSigils - Don't call functions with a leading ampersand sigil.

## AFFILIATION

This Policy is part of the core Perl::Critic distribution.

## DESCRIPTION

Since Perl 5, the ampersand sigil is completely optional when invoking subroutines.  It also turns off checking of subroutine prototypes. It's easily confused with the bitwise 'and' operator.

```
  @result = &some_function(); # not ok
  @result = some_function();  # ok
```

## CONFIGURATION

This Policy is not configurable except for the standard options.
