This is t already disallowed?

@jbrockmendel, thank you for taking a look at this PR.

Yes, it's correct, it is disallowed. I thought we wanted to improve the error message. Did I get your comment #62316 (comment) wrong?

Maybe I should rename my PR to "ENH: clarify error message …"

Update: renamed it

[jbrockmendel]

bool and integer singular

[natmokval]

thanks, I've changed it to singular

[natmokval]

bool and integer singular look better to me too, but I found that in pandas we use both the singular and the plural and sometimes we mix them:

pandas/pandas/core/arrays/timedeltas.py

Lines 481 to 482 in 7bf6660

	f"Cannot multiply '{self.dtype}' by bool, explicitly cast to "
	"integers instead"

can you add a test

[jbrockmendel]

BTW there are a few issues with the "Numeric Operations" label and "MultiIndex" label about silent alignment on arithmetic between Series/Frame with non-aligned MultiIndexes. While looking at them the other day I thought that might be a good topic for you to tackle.

Done

Sorry, I did not find the issues you mean. I found these two issues (#60498, #61009) which could be related, but they are already closed.

Could you please be more specific?
