Can anyone tell me the point of Address.sol in OpenZepplin and why would I want to check if an address is a contract, please?

Can’t find any info online

I see a ton of coins do: Using Address for address;

There are some cases where you want to make sure that the receiver of tokens is not a contract (or is a contract).

For example contracts may not be able to handle tokens and it's more sure to only transfer them to EOAs

So instead of making the sender lose their tokens it gives them an error instead? Is there a reason why someone would send tokens to a non EOA?

Some contracts are able to handle tokens. And no, the point is probably not to give an error, but to not do the transfer at all - maybe do something else instead
