If there are two ways to do the same thing, they should both work.

This is completely backwards. An expression which triggers an
error when evaluated with symbolic values is an ill-behaved expression.
The problem is in that expression, not in plot2d or any other function.
Maxima is a symbolic computation system only to the extent that
expressions can be evaluated for symbolic values.
