Noooo! Warnings suck. Errors are fine, nothing is fine, a big bag
of unspecified 'maybes' that are put on either side depending on
the user is not.
Unfortunately, dub makes warnings into errors by default, but you
can use `buildRequirements "silenceWarnings"` or
`buildRequirements "allowWarnings"` to mitigate it.
If implicit float truncation is really error prone, it should be
deprecated. Otherwise the compiler should shut up about it.
