For example:

import (
 someapi "xxxx"
)
type SomeStruct struct {
 Type someapi.SomeType	
}

The expression I want to execute is to validate the value of an enumeration.

someStruct.Type == someapi.SomeType_TypeOne

errors encountered:
failed: unknown name someapi
This error is easy to understand, but I don't know how to import the "someapi" package into expr context.

I tried to convert the type to int32, but it didn't work

int32(someStruct.Type.Number())==1

failed: unknown func int32

The only solution I've found so far is to convert to string

someStruct.Type.String()=="Day"

This looks more expensive, so I want to seek the best practice.
