Add ability to match multiple regex groups into array

[PhaedrusTheGreek]

Not sure if this is already possible, but it doesn't seem so.

Given the String: Hello:1 Hello:2 Hello:3, In Perl, you could do: /Hello:(\d+)/g , with the Global modifier (/g), this would give you an array: [1,2,3]. But in Logstash/Ruby, there doesn't appear to be a way to add the global modifier.
