I find this a little difficult to skim, because parallel things are not
aligned. Aligning on ':' should make things much easier on the eyes:

multi sub perl6(
Bool :a($autosplit),
Bool :c($check-syntax),
Bool :$doc,
:e($execute),
:$execute-lax,
Bool :F($autoloop-split),
Bool :h($help),
:I(@include),
#TODO -M,
Bool :n($autoloop-no-print),
:O($output-format) = 'exe',
:o($output-file) = $*OUT,
Bool :p($autoloop-print),
:S(@search-path),
Bool :T($taint),
Bool :v($version),
Bool :V($verbose-config),
);

Ah, that's a bit better. Looking at the above, is $execute-lax supposed
to be a boolean, or is it really a generic scalar? It's also not
obvious what a boolean named $doc does -- which probably means either
that it's not supposed to be a boolean, or it needs a somewhat more
descriptive long name (or both).

Also, in Perl 5 taint is tri-valued, because it has a warnings-only
mode. How will that be supported by Perl 6?

Finally, how do the defaults of $output-file and $output-format interact
so that the default behavior remains compile-and-execute? Changing the
default to compile-to-exe seems unperlish to me ....
