Exactly, that's what lambda calculus is all about. Basically, a bunch of code 
is understood as a function, but since it does not have a function name, you 
simply call it lambda(x,...). The whole lambda calculus is all about 
analyzind the results of applying lambda(x...) to some expressions.

So, I simply think of lambda functions as "unnamed functions".

Cheers,
