Error compiling nested template imports

[charlesstaats]

To duplicate, have the following 3 files:

test.asy:

struct A { }

access test2(T=A) as module;

test2.asy:

typedef import(T);

access test3(T=T) as module;

test3.asy:

typedef import(T);
T t = new T;

Compiling asy, and then running ./asy -noautoplain -d test, gives the following errors:

access test3(T=T) as module;
               ^
test2.asy: 3.16: static use of dynamic variable
T t = new T;
      ^
test3.asy: 3.7: static use of dynamic variable

Some notes:

• If the line reads T t; instead of T t = new T;, then only the first error survives (at least on the master branch).
• Running with -dir ./base instead of -noautoplain does not affect the result.
• Without the nesting, there is no error. I cannot say for sure the error is related to templated imports; there might be a way to duplicate this behavior using nested structs. I have not really explored this avenue since I could not think of an approach that seemed promising to me, but my intuition in that area has proven faulty before.
