Does using ccall(...) in a module prevent its precompilation?

General Usage

The problem is caused by circular module imports. Example (the modules are in separate files):

module A

using B

export f1, f2

function f1(x)
return x + A.g1(x)
end

function f2(x)
return x^2
end

end # module A

module B

using A

export g1, g2

function g1(x)
return 5 * x
end

function g2(x)
return A.f2(x) - x^3
end

end # module B

if a script uses both modules, its precompilation can never succeed.

using A
using B

print(A.f1(3) + B.g2(5), “\n”)

I suppose it is a bug that the precompiler doesn’t complain in understandable language about such situations where it isn’t smart enough to work.
