#10747: symbolic functions can be defined with a constant argument

-------------------------+--------------------------------------------------
The expression
{{{
h(6)=8
}}}
currently defines a symbolic function ``h`` with constant value 8. This
makes no sense, but begginers make this mistake, for example if h is an
array and they use () instead of []. It doesn't hurt to throw an error at
all expressions
{{{
h(something) = ...
}}}
whenever something is not a symbolic variable.
