C++ templates do work like that, so you indeed get bloat in the object
code (just as if you'd manually duplicated code like you'd have to in
C), but the source code becomes more uniform and maintainable.  The
bloat isn't a law of nature but rather reflects C++'s design goal of
zero-overhead abstraction.  

Other languages like Haskell can avoid the bloat by supporting
polymorphic functions implemented by passing type info at runtime,
taking a slight penalty in speed.  I'm not sure how Ada handles this.
Ada has generic but I don't know how they work.  There's also some
generics in C11 or C14 that looked nice though I don't remember any
details by now.

No I mean at least among some PL geeks, OO has become unfashionable in
general, not just in C++.  They see it as a 1990's thing that didn't
fulfill its promises.  Smalltalk has faded to obscurity and Java is a
post-Cobol Cobol, etc.
