Bug #6172: Inconsistent behaviour of defined?

• Status: Rejected
• Assignee: -
• Target version: 2.0.0

[pkondzior (Paweł Kondzior)]

Following behavior is obvious:

irb(main):004:0> Object.const_get("Misio")
NameError: uninitialized constant Misio
from (irb):4:in const_get' from (irb):4 from /Users/pawel/.rbenv/versions/1.9.4-dev/bin/irb:12:in '
irb(main):005:0> Object.const_get(Misio)
NameError: uninitialized constant Misio
from (irb):5
from /Users/pawel/.rbenv/versions/1.9.4-dev/bin/irb:12:in `'

Both cases throws an exception, obviously with different backtrace because execution paths are different.

But following behavior is doesn't make sens at all for:
irb(main):001:0> defined?(Object.const_get(Misio))
=> nil
irb(main):002:0> defined?(Object.const_get("Misio"))
=> "method"

Shouldn't defined?(Object.const_get("Misio")) return also nil ?

The former is analogous to Foo.bar(Misio), while the latter is analogous to Foo.bar("zot").
Object.const_get is mere method call.
