This means ECL is going to produce a very expensive type check for each of
the arguments of TEST.

Use .ecl or .eclrc and add COMPILER-NOTE to the type
C:*suppress-compiler-messages* (this is a lisp type specifier, not a list)
which represents the type of notes and messages that are suppressed, or set
C::*SUPPRESS-COMPILER-NOTES* to T and get rid of everything which is not a
warning or an error.
