Select function restrictions

[Folknology]

I was experimenting recently with different design patterns, some of which I have implemented with select functions in the past. Delving back into my Xmos library tool bag I starting mixing these patterns up with the newer interface and task features of the 13.x tools. However I hit some limitations when trying to use select functions in combinable or distributable tasks. The compiler complains that I cannot use select functions within combinable tasks, this caught me by surprise, I was wondering why this restriction exists as I am kind of fond of the 'select' functions as a means to package up things like state handlers etc.. Can someone explain why this restriction is placed on the compiler? will select functions continue to be supported?
