Quoting the arguments to a function

[zv <zv@xxxxxxxx>]

I want to supply the arguments of a function (an alias to Emacs `calc') without expansion, e.g:

	zv@computer# calc 20/2*15
	150


Today of course the result gives "zsh: no matches found: 20*15/2"

Is there any way to signal to ZSH that an alias or fn should have arguments supplied literally?
