#614 overloading a builtin function

[Vic]

After overloading a builtin function, when I call 'builtin' function, it calls my overloaded function instead of the builtin version...
For example:
in current folder, in file 'sin.m' I define:

function y = sin (x)
    y = 100; 
end

Then on command line:
~~~
--> sin(0)
ans =
100
--> builtin('sin',0)
ans =
100
~~~

Is there a way to fix this or a workaround I could use?
thanks
