Description

This small thrift file fails to compile.

enum SomeEnum {
    A,
    B,
    C
}
typedef map<SomeEnum, i32> SomeMap
const SomeMap MY_MAP = {
    SomeEnum.A: 123,
    SomeEnum.B: 456,
    SomeEnum.C: 789
}
 

Trying to compile this thrift file results in this error: 

[FAILURE:generation:1] Error: have identifier "SomeEnum.A", but unset enum on line!

 

If I didn't use the typedef and instead declared MY_MAP with type map<SomeEnum, i32>, there is no issues with compilation. This issue also happens if SomeEnum is the value type in the map, and it also happens for typedefs of lists of enums.
