So much this. Strings can contain anything… json, JavaScript, invalid utf8, you name it! I’ve seen type systems (poorly) re-implemented in already typed languag

  Full disclosure: as a young programmer I contributed to and was co-responsible for promoting an in-house Java library which misused strings in exactly this way. I didn't know any better, I was working with some people who only knew SQL and in the relational schema every column was type char or varchar.

    I too have gone back and looked at code only to think, “what idiot wrote this?!” … when I slowly realize that I’m the only author. Experience can’t be taught. :)
