[Nix-dev] Anyone care to review my post on the Nix expression language?

[Wout Mertens]

Hi James,

great reading, I learned a few things! (like that let is a recursive
definition, doh :) )

Nix does support the / operator, but it needs spaces or it will be
recognized as a path:
 $ nix-instantiate --eval --expr '4/3'
/Users/wmertens/4/3
 $ nix-instantiate --eval --expr '6 / 3'
2

Wout.

PS: (You know that the default-values example is still marked TODO, right?)
