Now that I think about it, what about:

version (CheckCode) { mixin(checkCode(__FILE__)) }

//Rest of file
...

checkCode would probably make use of static asserts.  Is it possible to 
write a message to compiler output?  That would be a handy 
static-compilation tool.

Or maybe it could be in the unit-tests.  Actually you can probably do 
that in unit tests already even without mixin Expressions.
