digitalmars.D.announce - Decimal Arithmetic module available

I've been working on an arbitrary-precision floating-point module for a while
and have uploaded the source to DSource. (www.dsource.org/projects/decimal)

It's an implementation of the General Decimal Arithmetic Specification, Version
1.70, March 2009. (www.speleotrove.com/decimal). It contains most of the
specified arithmetic operations (except exponential and logarithmic operations)
and miscellaneous operations (except for logical and rotate/shift operations).

I would appreciate feedback, especially with regard to the implementation of
the context for the operations.

The current implementation compiles with D version 2.30, so does not
incorporate the new operator overloading.

Awesome! Hmm, I really need to get my BigInt modules into D2 so that you 
can use them.

Ditto my united type:
http://www.dsource.org/projects/scrapple/browser/trunk/units/si2.d
(I'll tweak it and/or the license as needed to get it in).

Maybe we need a std.arithmetic.* for all the "a little more than just a number" 
types.

Phobos with subpackages?!  Blasphemy!  That's what those filthy Tango
heathens do and everyone knows that's just morally WRONG.

(Yes, I know about std.c.*.)

Then all of Java must be wrong too?

The list of std modules is getting a bit too long. Maybe a tree structure 
would work.  After all it is for a programming language.  Another idea 
would be to make another root,  like  dlang. or lang. Having std. in 
front of nearly makes it a piece of superflous, redundent information. 
There are many roots more to choice from, and maybe it be nice to have 
the root module path be more informative?

Yes. ;)

I have the impression that a lot of the Phobos modules in D2 are relics 
from D1 that will be removed in due time.

Why is 'std.' more redundant than Java's 'java.'?

Let me use this opportunity to pitch tools.smart_import!

http://dsource.org/projects/scrapple/browser/trunk/tools/tools/smart_import.d

Example:

    mixin(expandImport("tango.[core.[Traits, Thread, Memory, BitManip]
      , stdc.[stringz, tgmath, stdio]
      , text.[Util, Unicode, convert.Utf, Regex], math.[Math, IEEE]
      , io.[Path: exists, Console: Cin, Path: createFolder, device.File]
      , net.InternetAddress
    ]"));

No more import path redundancy! :-)
