Unclear error message when calling `rows`

[tankorsmash]

Hey there,

Running the following line (pad) says:

Error: Cannot 4 arrays with different number of rows 3 and ≡ rows

≡(≍ ? ⊙⊙∘) . ◫ ⧻ , "twothr" "two"

I'm not exactly sure what it's trying to say, but maybe that it's unable to join the arrays of sizes 3 and 4? Maybe 4 has a meaning but it's not clear to me as a newbie!

The source error looks like its trying to print the array out (?), but I'm not sure. The format string is different than the other one a few lines down.

This is a bug in the error message.
4 and ≡ rows are meant to be swapped.

Thanks, I appreciate this!
