@jared You didn't give us a tricky case where it didn't interpolate, and you got hideous mis-syntax?

That's wonderfully hideous, though.

I use multiple heredocs in a single line routinely to put test-app code and test code together. But never nested heredocs. Guess it's time to find a use for them! 😈

I'm glad you posted it on Mastodon too @jared! There's enough room for me to explain my reasoning here.

Based on the docs (https://docs.ruby-lang.org/en/master/syntax/literals_rdoc.html#label-Here+Document+Literals) and some experimentation, I think it's this.

PLEASE is opened and closed within OH_NO.
`concat` executes at the end of OH_NO and opens JARED_STOP.
That leaves the first and last line only in DO_CRIME.

But do you know the actual answer or how to find it?
