Hi!

This will probably be considered a sacrilege by most of you, but unfortunately I am real newbie to
Ruby (from Java world).

I have read the following:
1/ Kernel::lambda converts a block to a Proc
2/ when passing a block as a parameter it is automatically converted to a Proc

My question (wondering rather) is why having these two different mechanisms?

Isn't possible to directly assign a block to a variable, as in parameter case?

tia, and sorry if this is completely stupid,
