5.4.2. Perl hates @

If you are programming Perl (or Interscript!) you will hate having @ as the warning character for script sections. There are two ways around this.

You can use two @ characters at the beginning of a line.

  @@p = @x

or you can use a command like:

  @set_warning_character(python='!')

which will set the python warning character to ! instead of @. Advanced Note. This change applies only to the current file, and only to the end of the containing block, if any. The effect will not be passed up to an including file, and it won't be inherited by an included file either.
