[aspectc-user] Aspects for statements

[Olaf Spinczyk]

Hi Melanie!

AspectC++ does not have a language feature that allows you modify the 
control flow at *any* statement. We are currently experimenting with 
annotations on statement level, but this is probably not what you want. 
All statements would have to be tagged.

An alternative might be a custom code transformation based on our Puma 
framework. The Puma source code is part of the AspectC++ source code 
tarball. If you are familiar with C++, I think you could build a simple 
code transformation like the one you described with Puma in a few days.

Best regards,

Olaf
