Subject: Any global matching function ?

Hi,

I am trying to do something like 

perl -e '$_ = "VAR_3 - VAR_1 - VAR_2"; print m/VAR_([0-9])/g, "\n"'

-> 312

in Ruby, but I couldn't find a global matching function which returns an
array.

The best I came with is

str = "VAR_3 - VAR_1 - VAR_2"

while numbers = /VAR_([0-9])/.match(str)
  print numbers[1]
  str = numbers.post_match
end

Is there a better way ?

Thanks in advance.
