Writing some built-in functions for Bash, possible?

[Ky-Anh Huynh]

Hi,

I'm using Bash heavily in my systems. Things become slow and slow 
when I have tons of scripts :) And sometimes it's not easy to 
manipulate data.

You may have heard of recutils [1] which has a C extension to be 
loaded by Bash. Is it possible to write similar things in D, for 
Bash? I am not good at C; it's great if I explore this field:)

Some examples in C are in [2].

My experience: Dlang has `pipe` support however the syntax is not 
as clean as Bash :) Most of the times I see short (<1k loc) Bash 
scripts are easy to maintain than Ruby (and now D things) scripts.

Thanks for your reading.
