Hi,
I'm trying to ensure some function I install at runtime on an object is
actually callable (its name is a valid function name) but can't find a way to
do that.
As I'm using 'aset' to install the property, any string can be using as name,
e.g. 'invalid-name'. Calling obj.invalid-name() is invalid so I want to
propagate that as an error.
Unfortunately 'aget' does not allow to detect that 'invalid-name' cannot be
called as obj["invalid-name"] = function(){} will actually succeed and
obj["invalid-name"] returns the function. Apparently the only way to ensure
'invalid-name' is not callable is to check for 'obj.invalid-name' (which is
undefined), in ClojureScript via '(. obj -invalid-name)'.
As my function names are defined at runtime I can't rely on this syntax.
Any idea on how I can achieve that?
Thanks,
Julien
