Immediately invoked functions in CoffeeScript

Could someone show me how to immediately invoke a function in CoffeeScript. I'm trying to accomplish something similar to this JS object literal.

WEBAPP = {
    maxHeight : function(){
        /* Calc stuff n' stuff */
        WEBAPP.maxHeight = /* Calculated value */
    }(),
    someProperty : ''
    /* ... */        
}

Is it possible or what are the workarounds?

There is do:\n\nWEBAPP = \n maxheight: do -> 1+1\n someProperty: ''\n\n\nWhich compiles to\n\nvar WEBAPP;\n\nWEBAPP = {\n maxheight: (function() {\n return 1 + 1;\n })(),\n someProperty: ''\n};\n",

For anyone else coming across this question, you can also combine the do keyword with default function parameters to seed recursive \"immediately-invoked functions\" with an initial value. Example:\n\ndo recursivelyPrint = (a=0) ->\n console.log a\n setTimeout (-> recursivelyPrint a + 1), 1000\n",
