Text and math interchangeability

[stefnotch]

If I have a formula like this, where "cat" is plaintext (and should behave like boring old text)...

What should happen if I select the text a and paste it somewhere else? Should it turn into a math a?
Answer: It should become a math a.

And what happens if I select the $\sqrt{2}$ and paste it into the text?
Options:

• Stringify it (sqrt(2))
• Split the text and put the math stuff there. The semantics layer will then complain about a missing closing quote, because there's maths inside of the text. (chosen option for now)
• Put it in there anyways and render it funkily
• Put it in there, but wrap it in a math row container.
