it was here somewhere. this is, as you can see, a lambda. `typeof()`
can be used even for invalid code and will return special `error` type
(don't try to catch it, just trust me ;-). in `static if` this `error`
type means `false`. labmda that can not be compiled is obvious invalid,
uncompilable code, so it has a type of `error`.

and `inout` is a hack for some kind of functions/templates.

to make a long story short: don't try to remember it all, you'll forget
it next day. just take it as it is and be happy. ;-)
