Have to admit I'm not exactly a regex wiz, but I imagine it can be done  
somehow. I assume you mean having a repeated capturing group append to an  
array any number of times?

But, I still think scan is a good tool for the job, it can do any regexp  
anyway. I don't think a single regexp is really intended for doing  
variable numbers of captures anyway (?) ).

irb(main):054:0> "ab c".scan(/\w|\s/)
=> ["a", "b", " ", "c"]

or

irb(main):052:0> "this is a test".scan(/\w+/)
=> ["this", "is", "a", "test"]

or even

irb(main):053:0> "this is a test".scan(/\w+|\s/)
=> ["this", " ", "is", " ", "a", " ", "test"]

Cheers,
Ross
