If it's valid (I don't know if there can be a block-lambda standing alone
outside of a function), it would return the value of the global variable `age`,
I think, because the enclosing scope's `this` in that code above seems to be
the global Object.
Brendan, do you really want these block-lambdas to be blocks?
I thought you were just going to borrow its syntax for shorter function(){}
semantics, not blocks semantics ?
What if {||} were just the shorter function syntax we want, with the added
features we want (completion value as return value, lexical/dynamic `this`, ...
?), but not true blocks ?
