The best way (or the only way really) is to not use a compiled language
at all, but to use machine code instead, or *maybe* assembler language.

Where "lots and lots" means "exactly zero": you can always do an
ssignment to something with an appropriate type.

Explicit casts are exceptional, and that is how they should be used.
Whenever you see one, you know something unusual is going on.  Implicit
casts can be treacherous that way (but they are prefered often).  Good
taste cannot be taught, all that.

(This is assuming you're looking at reasonable code of course.  Oh
well).
