Just for the sake of "academics", it is possible to call a dynamic
method using only expressions, but it requires some gymnastics that some
would consider onerous.
For instance:
<cfscript>
foo = createObject("component","foo");
methodToCall = "getStuff";
foo.tempMethodName = foo[methodToCall];
result = foo.tempMethodName();
structDelete(foo,"tempMethodName");
</cfscript>
That last step is optional, since there's not much harm in having the
tempMethodName floating around (it won't be in the meta data, for instance).
I'm not advocating this as "good" code, necessarily, but it works fine
and given that methods pass by reference it isn't expensive. Whether
you consider it "readable" and/or "clean" is a matter of taste, I suppose.
