This is true. The compiler wants to be super-sure that you are only 
setting it once.

However, this can be alleviated by changing how you do things. Factor 
out the code that sets it, and have it instead return a value. Then you 
can do this:

shared static this() {
    num_triggers = myCrazyFunction();
}

Of course, myCrazyFunction must not depend on any other static 
variables, as those might not be initialized.

startup initialization can be very tricky.
