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?
