Build, test, and debug regular expressions
This regex matches function argument declarations in LScript, capturing type specifiers (bool, byte, short, int, long, float, double, array, or box), optional array dimensions in square brackets, and variable names that start with a letter or underscore followed by alphanumeric characters, underscores, or dots. It's useful for parsing LScript function signatures, validating parameter declarations, or building syntax highlighters for LScript code editors.
