Well, I come from Lisp : can you imagine someone missing perform: more than
a Lisp addict ? And yet, I did not speak up because :
(1) I don't know if there is a secure and efficient implementation of perform.
The amount of checking needed is too big.
(2) I have worked around most of the cases where I thought I would use it,
when it was quicker to code with perform: but also feasible (and probably
more efficient) with other contructs.
(3) I have reformulated more deeply the cases where I thought I NEEDED it,
to the same effect : better code in the end.
It changed my habits. It still is a little bit painful. IMHO, the operator
overloading discussion was revolving around that same thing. The theoretical
power of description of the language is the same with or without.
I am truly sorry if this seems patronizing.
