My previous proposal was turned down on the basis that it broke existing
code. Given that upgrading code is possible with a version keyword, it
could be worth re-examining the proposal...
do/end blocks keep their flat scope, but the parameter list is extended
to make the variables shadowed/private.
i = 1
1.upto(10) {|i| i = i * 3 }
puts i
will result in "1". If someone really wanted to define some local
variables, they could kludge this by popping a few more variable names
in the parameter list. Not nice, but it's easily understood and is not
an essential feature.
Another example:
i = 123
j = 10
(1..10).each do |i| # i becomes shadowed within the block
j = i * 5
k = i * 10
end
p [i, j, k] -> [123, 50, 100]
Next step...
Change the other block, {}, to have its own scope with all variables
being shadowed/private.
Eg:
i = 123
j = 10
(1..10).each {|i|
# accessing j at this point would be an error
j = i * 5
k = i * 10
}
p [i, j, k] -> [123, 10, accessing k is an error]
Eg, the code in the {}'s is just like it was a separate method. This
would also be a useful construct for testing the effect of refactoring
a block of code.
This would increase the semantic distance between the two block types
and make it clearer why there are two kinds of blocks.
It could also possibly eliminate the Proc/Method difference by making
{}s into syntactic sugar for an anonymous method definition or closure.
The <> construct can be used for the existing block definitions.
Regardless of whether this proposal makes it or not, I think updating
existing code is an interesting approach to the problem of how to upgrade
a language without breaking older code.
If old code can just be deprecated into clumsier syntax, then the new
changes to the language can always have access to the best syntax.
