Hmm, that's new to me... but I don't think that's argument grouping, as it
doesn't work for methods which take multiple parameters:

  puts begin "hello","world" end  #>> syntax error

So it must be for expression grouping. In that case we could give
parentheses to the mathematicians for argument lists:
     sin(a) + b

and use begin/end everywhere else:

     puts begin "hello"+"world" end . size

     puts begin a+b end . abs

Not pretty :-)

Cheers,

Brian.
