I believe you can get the Perl 5 functionality by throwing a few *

Based on Apoc. 2, I'm not sure the Perl 6 isn't just as simple. It's just
different.

I may be misunderstanding pairlist vs. list context here, but I'd imagine
you could keep that type of functionality in Perl 6 with an explicit
keyword. Perhaps:
%environment = list (`env` =~ m"(.*?)=(.*)\n"sg); # Guessing
It seems to me that pairlist context will have enough benefits to outweigh
the extra care that must be taken to do Perl 5-ish stuff like the above.
