This page was my playground before creating Template:Ifeq
A conditional template. The first two arguments must be simple names appropriate for named parameters of a template, or empty. If they match, then this ends up calling the {{Use}} template with the indirect argument named twice, so the overall expansion is the second use of the indirect name, or the original third argument. But if they differ, then this ends up using {{Use}} with the indirect argument named only once, so the overall expansion is the original fourth argument.
That is, this is an alternate implementation of {{#ifeq:test1|test2|if equal|if differ}}, with a slightly different syntax:
{{ifeq|test1|test2|if equal|if differ}}
