How to ignore the result from a procedure in Nim

Question

As per title, assume I have the following:

proc squared(n: int64): int64 = n * n

Now let's assume I want to call the procedure squared but I am not interested in the result.

If I just write:

squared(15)

I get an error:

Error: expression 'squared(15)' is of type 'int64' and has to be discarded

I understand that this type of code is a bad practice, and I should explicitly ignore the result. Hence, how do I explicitly ignore the result?
