Built-in functions as "first class" glitch in function return values

function function regurgitateFunction(required function f){
    return f;

writeOutput("<h3>Built-in function</h3>");
midref = mid;
    resultWithBuiltInFunction = regurgitateFunction(midref);
    writeDump(var={object=resultWithBuiltInFunction, type=resultWithBuiltInFunction.getClass().getName()});

function safe(f){
    try {
    }catch(any e){
        writeOutput("#e.type#: #e.message#; #e.detail#<br>");

Errors with:

function: The value returned from the regurgitateFunction function is not of type function.; If the component name is specified as a return type, it is possible that either a definition file for the component cannot be found or is not accessible.

This makes no sense as the function was accepted as an argument of return type "function" to the function, but then as not legit as a return type of "function"

If we're going to get into functional programming (and to be clear: allowing functions as arguments means we are),then ALL functions need to be fair game.

Built-in functions and user-defined functions should behave consistently in all places where a function can be passed or is expected as an argument.

Can you please confirm in what version of ColdFusion this is going to be implemented in. It says "to fix" but does not say which version.

Hi Adobe, The "+1 ......................" is my vote, which I'm unable to edit for whatever reason. I'd like to elaborate: This needs fixed for *ALL* built-in functions. CF-4202219 needs re-opened/fixed. Thanks!, -Aaron
