# Operator::DynvarOr

[![Build Status](https://travis-ci.org/gfldex/raku-operator-dynvaror.svg?branch=master)](https://travis-ci.org/gfldex/raku-operator-dynvaror)

## SYNOPSIS

```

use Operator::DynvarOr;

sub s {

    my $*dynvar //* 42;

}

s;

```

This module supplies the infix operator `//*` that expects its LHS to be a

dynvar and its RHS a value. It scans the call stack for a dynvar of the same

name and sets the LHS to its value. If the dynvar is not declared in any

caller it will assign the RHS to the LHS. This allows optional dynvars to

contain undefined values which is otherwise difficult to achieve.
