I therefore feel like I ought to not use assert and should
instead validate my assumptions with an if statement and a
throw or exit or something.
Yes, that's the way of doing. assert() are just used to test
the program. the -release option in DMD disable all the
assert() (excepted assert(0) which is a bit special), so that
in a release version, only Throwable objects can be used after
a failure detected.
A small addition to the answers already provided.
As user1234 has already said, asserts are removed in the -release
build, so, if you have to validate some assumption (ex. the file
opened) you should use enforce[0].
