Details:

The following code should create a cell array with one element, the string
"foo" (my original problem was more complex, of course, but I downsized it to
that one).

===========
function txt=foo()
        txt = 'bar' ;
end

{ foo () }
===========

Executing this yields

===========
  syntax error

>>> { foo () }
         ^
===========

Obviously, the parser dislikes the space character after "foo"; it assumes
something similar to "[1 2;3 4]" and does not recognize that in fact this
should be a function call. If that character is deleted, the code works. Is
such a behavior intended?

Even more strange, it is also OK if the function "foo" is called before
outside of the cell array initialization.
