Ability to require spcific words as arguments#158

Sometimes, I have to create more than one ar over and over again because I can’t require specific words as arguments, for example, I want “.bake cake” to work but I don’t want “.bake airhaihohauiroeja” to work. But I can only require “words” as arguments, not specific words. If this feature is implimented, ars would look more clean as all they need is one to work, and they would also be really helpful and time-saving as you only need one ar.
