Is your request about syntax?
Yes

No

Describe the request

Current parser does not support empty generic construction if generics already defined in type.

Example:

class Test<E, T> {}

v construct : Test<int, string> = new Test(1, "test");
//Error:                              ^^^^ Test requires 2 generic definings

In future ellie should accept this.
