When vecN is used with tuples, 'dub test' fails.

[KanzakiKino]

I having run dub test, many linker errors happen.

Source

/dub.json

{
  "name": "temp",
  "dependencies": {
    "gl3n": "~>1.3.1"
  }
}

/src/main.d

import std;
import gl3n.linalg;

void main() {
  Tuple!vec2 tuple;
}

Output

$ dub test
