what is this def?
it is not a method...?
it is not some sugar...?
well might it be a lambda...?
just what is this def?

(funny we say def for define but not init for initialize)

a keyword?
well, btw it is also sugar fore define_method() :)

>(funny we say def for define but not init for initialize)

I would have loved init :(

sidenote: what about that old thread about making def return something
useful ? (I remember that an UnboundMethod was refused, but what about
a Symbol? )

It is a special form. Or, to paraphrase the Gateless Gate,

A monk asked Nansen: `Is there a teaching no master ever preached before?'

Nansen said: `Yes, there is.'

`What is it?' asked the monk.

Nansen replied: `It is not a method, it is not some sugar, it is not
lambda.'

I'm thinking that Ruby should accept any method that is a one-character
misspelling of initialize as an initializer. Perhaps I'll write an RCR.
