Next project(s):

• using my new conditional templates to add optional subgroup to Template:Mouse
• what else needs doing?

It looks like this wiki lacks Extension:ParserFunctions, which means no {{#if:test|if text|if empty}}. But I think I can work around it with my own template, using double template nesting. To test that...

What happens if I use a template:

• with no argument: --
• with no named argument: --
• with named argument empty: --
• with named argument first: -hello-
• with named argument second: -hello-
• with named argument twice: -second-
• with different named arg: --
• with two names: --
• with indirection: -hello-
• with indirection, swapped order: -hello-
• indirection without name: --
• indirection with empty name: --

Experiments with If:

• no args: --
• 1 empty arg: --
• 1 non-empty arg: --
• 2 args, first empty: --
• 2 args, first text: -true-
• 3 args, first empty: -false-
• 3 args, first text: -true-

Experiments with Ifeq:

• no args: --
• 2 args, equal: --
• 2 args, differ: --
• 4 args, equal: -hello-
• 4 args, differ: -hello-
• 4 args, both empty: -hello-
• 4 args, both undefined: -hello-
• 4 args, first empty: -hello-
• 4 args, second undefined: -hello-
