And how would std.conv.to know that the result won't change? It k
nows nothing about the variable it's being passed, and that variable could 
depend on user input or what's in a file or some other value which is runtime-
dependent.

I don't believe that anything in Phobos changes behavior based on -debug 
(there are a few places where -debug=something results in a module printing 
extra stuff for unittests - e.g. -debug=string for std.string - but not for -
debug), and -debug is really meant for debugging purposes, not for enabling or 
disabling checks. That's for -release, which, for better or worse, you can't 
actually check for in code. So, really, there is no way to have -release affect 
any code in Phobos beyond what it does to the language in general (remove 
assertions and remove array bounds checking in @system code), even if we 
wanted it to, which is debatable.
