formats added to perlito5
perlito5 is a Perl compiler written in Perl.
The format statement was required in the grammar for completeness. The 'format' command is not supported at the emitter side - it compiles, but it doesn't run yet.
Some other features are still marked as TODO and are simple to implement:
- dot-decimal strings (without the 'v'),
- "'" meaning "::",
- using 'CORE::' in odd places - 'CORE::if' in place of 'if' and 'CORE::and' in place of 'and'.
With these in place, the grammar will be "100% complete" - the tests will eventually tell if we got there or not.
