I was surprised that it would not bail out at the full-stops.

Is there any way to see how perl attempts to parse a script that eventually turns out not to be valid (B::Deparse will not help then I suppose...)

    I was surprised that it would not bail out at the full-stops.

    The full stop is the concatenation operator. This is valid perl:

    $ perl -ce 'a . b;' -e syntax OK

    If your only punctuation is the full stop and the comma you can get away with most things. Just avoid reserved words near punctuation.

    $ perl -ce 'Twas brillig, and the slithy toves Did gyre and gimble in +the wabe; All mimsy were the borogoves, And the mome raths outgrabe' -e syntax OK

    Of course, you couldn't end that with a full stop because it's a binary operator. HTH

    It has been suggested to rename Perl 6 in order to boost its marketing potential. Which name would you prefer?
