When attempting to compare a BigDecimal to an object that does not implement #coerce, the error message incorrectly indicates that the object is nil and the message has a typo.

> 10.to_d < "foo"
nil could not be coerced to BigDecmil

("BigDecmil" is a typo in the code)

A correct message might be: "String can't be coerced into BigDecimal"
