Maxima already has a cond statement:
if a then b
elseif c then d
... (any number of elseif clauses)
else e (optional)
The final "else" clause is exactly equivalent to
elseif true then e
The only difference with Lisp's cond statement is that the
then-clauses contain only a single statement since there is no
explicit syntactic bracketing: you could I suppose interpret
if a then b, c elseif ...
as
if a then (b,c) elseif ...
but how would you interpret
if a then b, c
?
If you want syntax that's completely parallel to Lisp cond, just
always use the parens:
if a then (b)
elseif c then (d)
... (any number of elseif clauses)
else (e) (optional)
which allows you to have multiple comma-separated statements in the
then-clauses.
