# I expect this​:
pos = 2; @​words = (); push @​words, $1 while /\G\s*(\w+)/g;
print "scalar g (@​words) = ", defined pos() ? pos() : "undef", "\n";
# "ed barney", respected initial pos, pos is undef at end

# I expect this​:
pos = 2; @​words = (); @​words = /\G\s*(\w+)/g;
print "list g (@​words) = ", defined pos() ? pos() : "undef", "\n";
# "ed barney", respected initial pos, pos is undef at end

# I expect this​:
pos = 2; @​words = (); push @​words, $1 while /\G\s*(\w+)/gc;
print "scalar g (@​words) = ", defined pos() ? pos() : "undef", "\n";
# "ed barney", respected initial pos, pos is 11 at end

# I think this is a bug​:
pos = 2; @​words = (); @​words = /\G\s*(\w+)/gc;
print "scalar g (@​words) = ", defined pos() ? pos() : "undef", "\n";
# "ed barney", respected initial pos, but pos is still 2???
__END__

From my read of the docs, I think pos() should be left at the end of
the last successful match if /c is present. Any takers? Anyone got a
patch? Either the docs or the behavior is off here.
