what's the difference between set_lazy and set_allow_lazy_parsing given that the
struct is called ParseInfo?

[Toon Verwaest, 2016/10/10 14:18:52]

is_lazy is a misnomer. It should be called "eager_parse_function". It's when you
have a Handle<JSFunction> and you want to parse/compile it; as opposed to a
script.
