# Filter::Template::UseBytes(3pm)

conditionally use bytes.pm depending on availability

## NAME

Filter::Template::UseBytes - conditionally use bytes.pm depending on availability

## VERSION

version 1.043

## SYNOPSIS

```
        use Filter::Template ( isa => "Filter::Template::UseBytes" );
        print "Phi length in characters: ", length(chr(0x618)), "\n";
        {% use_bytes %}
        print "Phi length in bytes: ", length(chr(0x618)), "\n";
```

## DESCRIPTION

The UseBytes template evaluates to `"use bytes;"` if Perl 5.005\_55 or later is running.  Otherwise it evaluates to an empty string, which does nothing but doesn't throw an exception either.

## BUGS

All the caveats of Filter::Template apply here.

## SEE ALSO

Filter::Template.
