NAME

====

Trait::IO - Helper IO traits

SYNOPSIS

========

```raku

use Trait::IO;

for  {

    my $fh does auto-close = .IO.open: :w;

    # ... do things with the file handle

    # $fh is auto-closed on block leave

}


# Top-level is OK too; will close on scope leave

my $fh does auto-close = "foo".IO.open: :w;

# ...

```

DESCRIPTION

===========

Useful traits for working with Raku IO.

EXPORTS

=======

does auto-close

---------------

```raku

my $fh does auto-close = "foo".IO.open: :w;

```

Installs a `LEAVE` phaser to automatically close the file handle when scope is left.

Exports the  constant and the `trait_mod:` multi that accepts it as a value.

Currently works only with variables and not with attributes or parameters. Patches welcome.
