:( Oh, indeed, it's documented, thanks. Yet, CL#1 works OK, and the reason why Perl can be confused here and care is required is neither clear nor explained, in documentation. How CL#4 can be parsed to what's printed out, is unclear. OK, just a thought...

Edit: OK, CL#1 was parsed specially because there was single letter identifier:

>perl -lwe "sub x{@_} print sort x(qw(q w e r t y))"
eqrtwy

>perl -lwe "sub xx{@_} print sort xx(qw(q w e r t y))"
qwerty
