    GK> "my" seems too complex for user. 

I do not understand why "my" is too complex to a user. It has been in Perl for
years and no one complained of its complexity. Similar semantics exists in
Scheme and Lisp (let (...)) and has been in use for decades .
If you do not like token "my" it can be any other name like "local", etc.
Bottom line, Ruby does not have a mechanism to push an arbitrary
local variable onto its local scope. And this is bad!
