no, if I understood Larry correctly, you can of course write a nice
grammar-modifying module, but other modules you use() still use
Perl 6's standard grammar. E.g.:
use Grammar::Ruby;
# Ruby syntax from here on:
proc { |a| puts a + 1 }.call 3 # 4
use SomeOtherModule
# SomeOtherModule.pm will be parsed using the standard grammar,
# *not* Grammar::Ruby.
If you wanted the compiler to parse SomeOtherModule.pm using Ruby's
grammar, you'd have to write:
use Grammar::Ruby;
reuse SomeOtherModule
