square brackets for test?

I have this code:

fn efixme message:str
	test "$ZERNIT_IGNORE_FIXME" != 1 && printf "$ZERNIT_EFIXME_FORMAT" "$message"
end

Where i believe that this would look less ugly:

fn efixme message:str
	[ "ZERNIT_IGNORE_FIXME" != 1 ] && printf "$ZERNIT_EFIXME_FORMAT" "$message"
end
