Subject: should $1 propagate through method calls?

Hello all.


When running this snippet, I expected that, since $1 "looks" like a
global variables, it would be propagated across method calls.  Should it
be?

def go
 print 'got', $1
end

'a' =~ /(a)/
print 'got1', $1
go

expected output:

got1agota

actual output :
$ ruby -v test.rb
tcs-ruby 1.9.3p28 (2012-01-28, TCS patched 2012-01-30) [i386-mingw32]
got1agot

Jruby "sometimes does and sometimes doesn't" propagate this.

Is this expected? Which way is right?
Thanks.
