The error message is misleading when setting too many attributes

[yegor256]

Consider this code:

sprintf
  "Hello, %s, your salary is %d"
  "Jeff"
  42

This will lead to error:

Can't overwrite the "λ" attribute

It's a very weird and misleading message. Apparently, it happens because sprintf doesn't have three void attributes, but only two. The right code is this:

sprintf
  "Hello, %s, your salary is %d"
  *
    "Jeff"
    42

I suggest adding this test method to PhDefaultTest:

    @Test
    void failsCorrectlyWhenTooManyAttributesPut() {
        MatcherAssert.assertThat(
            "the message explains what's going on",
            Assertions.assertThrows(
                ExAbstract.class,
                () -> new EOnumber().put(1, new Data.ToPhi(1)),
                "fails when trying to set attribute with too big position"
            ).getMessage(),
            Matchers.equalTo("there are no void attributes left, can't set the 1st one")
        );
    }

Let's make it pass.
