% This command has an assignment operator and it is considered to be an
assignment.
z .a = 0;
% So far so good. However, this command has an assignment operator too:
z .(a) = 0;
% Nevertheless, it is considered to be a function call.
% If that is consistent, I do not know what is not.

In general, when MATLAB recognizes an identifier (which might name a
function or a variable), it analyzes the characters that follow the
identifier to determine the type of expression, as follows:

An equal sign (=) implies assignment. For example:

ls =d
]

So the syntax interpretation of "z .a =" as assignment is defined and
documented. It is then consistent.
