I somehow thought that one additionally needs a "change team", but I now 
think that a "form subteam" should be sufficient - which makes the code 
cleaner than I initially feared.

Thus, the advantage of the proposed new intrinsic (e.g. "this_team()") 
is smaller.

PRO new intrinsic: The code is clearer than "form subteam(1, var)". And 
it avoids a synchronization (which is relatively slow)
CON new intrinsic: It pollutes the namespace without providing a 
substantial new features.
