Not allowing an implicit conversion between integer and floating is
"stupidly typed". Forcing explicit conversions for this into programs
adds so much clutter that it's not worth it.

Many languages have this conversion freedom, including ones that do not
have C's reputation for making it difficult to develop reliable
programs.

Python:

        >>> 1.0 + 2
        3.0
        >>>

Common Lisp (using CLISP implementation):

        [1]> (+ 1.0 2)
        3.0

Ruby:

        > 1.0 + 2
        => 3.0

One source of bugs is verbose clutter, where they can hide.
