=SUBTITLE Compilation error due to a regex quantifier without preceding atom

    class X::Syntax::Regex::SolitaryQuantifier does X::Syntax { }

Syntax error when a stand alone quantifier (without an preceding atom
to quantify) is encountered in a regular expression.

For example

=for code :skip-test
/ * /;

dies with

=for code :skip-test
===SORRY!=== Error while compiling
Quantifier quantifies nothing
