	// backwards compability, but some new template funcs may also make
	// sense to give short and snappy aliases.
	// Note that these aliases are global and will be merged, so the last
	// key will win.
	Aliases map[string]interface{}

	// A slice of input/expected examples.
	// We keep it a the namespace level for now, but may find a way to keep track
	// of the single template func, for documentation purposes.
	// Some of these, hopefully just a few, may depend on some test data to run.
