The language spec says:
"The compiler may optionally not evaluate assert expressions at
all."
In practice, this means that it depends on compiler flags. For
DMD, assert expressions are ignored in -release.
Sometimes, I want to do things only when asserts are being
compiled, for example:
version(release) {} else import std.format;
assert(x == 0, format("x is %d, not 0", x));
I have two problems with this:
1. It's ugly to use the version... else syntax.
2. It's tied to the fact that DMD doesn't compile asserts in
release.
What I would prefer:
version(assert) import std.format;
Of course, version(assert) is compiled when asserts are compiled.
This makes the intent clear, and removes coupling with particular
compiler options.
Thoughts?
