Currently I’m using ‘the old dog’ but that sounds really great and might 
be the determining factor to try out ‘the new (Lua) tricks’. TBH, I like 
Mutt but its configuration of dynamically stuff was a real challenge for 
me two years ago. Therefore the idea and decision of using Lua within 
Neomutt some day, thrilled me since I have noticed that.

I have a question about this. Will it be mandatory to mixing ‘normal’ 
{,Neo}mutt configuration directives with Lua code or can both be placed
in separated files and sourced from there? That probably would prevent 
(new) user from getting confused, I think.

The reason behind this is, as I came to Lua due to my former favourite 
editor SciTE [1], I was glad to separate normal statically (treated as 
default) configuration from Lua scripting and to know which is which by 
using a simple startup script declaration [2].

This way it was also possible to implement a global table (as a normal 
user) which realised a pseudo object-oriented programming syntax within 
additionally Lua scripts due to the require() statement. And using the 
several exposed events from SciTE — that was fun pure.

I’m sure I will when I found the way how to compile, install and testing 
Neomutt without influencing my existing ‘old dog’. ;-)

Thanks for working on this.
