To be more precise: All built-in function (not to confuse with the functions
in "functions.cin"!!!) that take more than one argument will return the
first argument if the first argument is constant.  Further, radians and
degrees functions also return the input rather than the converted output if
the input is constant.

One workaround is to simply add i.e. "x-x+123" to replace "123".  Of course,
this bug will be fixed in the next beta.
