Thanks Simon. Actually, this was the first thing that I tried:
SemistandardTableaux_nmu=deprecated_function_alias(9265,SemistandardTableaux_size_evaluation)
but it leads to the error:
sage: sage.combinat.tableau.SemistandardTableaux_nmu(4,[2,1])
ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line statement', (69, 0))

This is a little strange a both the deprecated function alias and the new
class have __name__ attributes...
