Well, that explains why it is not listed among the visibility attributes to begin with -something that at first glance seemed weird to me.

`lstrSequence` is local to the function, so visibility (`public`, `private`, ...) doesn't even apply.

Being *local* to ... ain't imply visibility too regardless scope not being a visibility attribute ? I mean, scope is restricting the variable to be leaked outside the function/whatever and to me it seems like restricted to be seen from the outside. *Please note* that I am not making an argument against the implementation, I am just trying to understand why it is not being classified as another visibility attribute given that more-or-less has the same concept as a local variable like in other languages.

Most likely, you don't have any use for `scope` at the moment.

Almost sure if you say so given your vast knowledge of D against my humble first steps LoL.

You're obviously not compiling with `-preview=dip1000`.

Nope. I didn't knew it even existed.

And neither should you, because the feature is not ready for a general audience yet.

ACK.

[...]
Style: `scope` does nothing on `size_t` parameters (throughout).

A week ago I was using [in] almost everywhere for parameters, ain't [in] an alias for [scope const] ? Did I get it wrong ? I'm not talking style here, I'm talking unexpected (to me) functionality.

I'm not sure where we stand with `in`

You mean *we* = D developers ?

but let's say that it means `scope const`

This I stated because I read it somewhere in the docs, it was not my assumption.

The `scope` part of `scope const` still does nothing to a `size_t`.
These are all the same:

in size_t
const size_t
scope const size_t

OK. Specifically to integers nothing then. But, what about strings and whatever else ? I put them more-or-less as a general rule or so was the idea when I replaced the in's in the parameters app-wide.

scope size_t lintRange1 = lintStart - cast(size_t) 1;
scope size_t lintRange2 = lintRange1 + lintCount;

Possible bug: Why subtract 1?

Because ranges are zero-based for their first argument and one-based for their second; ie: something[n..m] where m should always be one-beyond than the one we want.

That doesn't make sense. A length of zero is perfectly fine. It's just an empty range. You're making `lintStart` one-based for no reason.

For a UDT like mine I think it has a lot of sense because when I think of a string and I want to chop/count/whatever on it my mind works one-based not zero-based. Say "abc" needs b my mind works a lot easier mid("abc", 2, 1) than mid("abc", 1, 1) and besides I am *not* returning a range or a reference slice to a range or whatever I am returning a whole new string construction. If I would be returning a range I will follow common sense since I don't know what will be done thereafter of course.
