{{ switch }} as a variable for a partial

Hi, I was wondering if it would be possible to use the switch tag within a partials variable.

My current code looks like such:

{{ blocks }}
  {{ if first }}
    {{ partial src="{type}" is_first="true" tester="{{switch between='odd|even'}}" }}
  {{ else }}
    {{ partial src="{type}" is_first="false" }}
  {{ /if }}
{{ /blocks }}

So far I have been loving Statamic by the way! <3
