What are you stuck at? What was the most difficult features to
understand? etc.
To make it more meaningful, what is your experience with other languages?

If your configuration is missing, you could make a Pull Request
to add it.
So it does. Thanks.
We might also link to that on the dub.pm website.

Just use an enum for your token types. Something like this
would suffice:
That's basically what sumtype is going to do for me, but
(hopefully) more safely. Also, the token

Of course, 'static assert' is better there because it will catch the
issue at compile time.
static assert(0, "\nBoolean type cannot be used!"

You can use void initialization to declare values of types that
don't have an `init` value: `x value = void;`
As for an alternative to the brute force `__traits(compiles,

Hi All,
The problem is that I want to disable the use of boolean type.
But this is not possible with contract programming or otherwise.
Actually, it's possible to fix it with contract programming or
otherwise throwing errors.

It gives an error when the exclamation mark is removed, I have no
