This sounds like perfect fodder for something like metalua. The string
could be hoisted out of the expression where it's used, compiled to
bytecode at the top level, assertion checked for upvalues, etc, all
quite easily:

fn(chunk print("Hello, world!") end)

==>

local __chunk1 = function() print("Hello, world!") end
checkNoUpvalues(__chunk1)
...
fn(__chunk1)

Metalua might be a bit heavyweight for just this, though --- I have
vague recollections that there's a more lightweight form of syntax
extension available, but can't for the life of me remember what it is.
