Kernel.method() question

Hi,

I was just wondering, why doesn’t Kernel.method() call method_missing() when
it can’t find a method, instead of raising a NameError?

Well, probably you make a confusion

Kernel#method create a Method object, for example

pigeon% ruby -e 'def tt() end; p method(:tt)'
#<Method: Object(Object)#tt>
pigeon%

Now ruby effectively call #method_missing when it don't find a
method

pigeon% ruby -e 'qq()'
-e:1: undefined method `qq' for #<Object:0x401bace0> (NameError)
pigeon%

pigeon% ruby -e 'def method_missing(id) p "missing #{id}"; end; qq()'
"missing qq"
pigeon%

D’oh!

Of course, because Kernel.method() is only returning a Method object, but
not actually calling that method.

I think my confusion was because the only places I have ever used method(),
I have in fact used it like this:

method(methodName).call(*args)

…so I guess I had stopped thinking about the Method object as an object
at all.

Cool.
