NAME

Language::Expr::Interpreter::Default - A default interpreter for Language::Expr

VERSION

version 0.10

DESCRIPTION

Interprets Language::Expr expression. Some notes:

  • Uses boolean module.

    Comparison like '1 > 1' and '

  • Follows Perl's notion of true and false.

    That is, this expression ' "" || "0" || 2 ' will result to 2 because Perl thinks "" and "0" are false.
