This also sounds similar to some of the issues I dealt with in some 
experimental code I wrote to simulate the result of precompiling modules. 
In `eval_expr`, I dealt with the ability to handle some expressions 
specially (such as `=`) and to recurse into `module` declarations. (The net 
goal of this code was to serialize the result of each statement so that 
deserialize could replay the same results, but faster).

Re: [julia-users] Re: ASTs of complete modules/packages?

[Cedric St-Jean]

It would make sense to put .jl file-parsing code in a separate,
community-maintained module, because the rules for finding which file a
module corresponds to are not trivial, and can change over time (they
became case-sensitive in 0.5)

It's too bad that

macro module_parser(m)
m
end

@module_parser module X
a = 10
end

is a syntax error, because it would be cleaner for instrumentation, and for
augmenting Julia's syntax.
