You´re right.
If I dont have an important feature which I would miss in the future its quite useless to whine about something I dont have and actually dont know how to apply correctly.
Perhaps I expressed myself unclear (sorry for that) I do have one or two cases where Lookaheads are usefull but I am still thinking I could also write them in Boost. Unfortunatly I havent found out how yet:

Perl goes: /(?=.*\.)/

Boost goes: /[^.]*/

Actually I just got aware that the second regex without Lookahead is much more usefull because its more flexible. I simply didnt thought well enough about my problem.

I should take myself more time to think about problems. One week still isnt enough ;-) I probably should wipe my ideas if I havent solved them in one day.
The obvious often hides behind the complicated.

Anyhow. I just made the decision to use the library which is currently implemented. I was more frightend to have something I wouldnt be able to work with. And I needed to see this written down somewhere *g

Thanks for pointing me in the right direction
