Although I agree that there's a lot of noise here. Example, it is not obvious from the example that you are editing the root Object, IANAR but doesn't this mean that every (new?) object now has a remember method and –potentially– a @block attribute. It's definitively not intuitive that @block exists because it was binded to a globally implicit self object, the lambda expression is ugly but Python's is worse anyway. the block parameter syntax is fine, it's just a shame that it can't take multiple blocks like SmallTalk's. @block.call is stupid, no true functions or functors is sad.

3-5. It's pretty straight forward. Since someone already pointed out you can do it in Python, here it is in perl:

sub remember {
$block = shift;
}

remember(sub {print “Hello, $[0]!” });

$block->(“Jon”);

Here it is in Lua:

function remember (ablock)
block = a_block
end

remember(function (name) print(string.format(“Hello, %s!”, name)) end)

block(“Jon”)

And PHP:

google, copy + paste
