I rather like how Scheme treats boolean literals (#f and #t) as syntactically distinct from normal variables. The syntax feels tidier than overloading variable names.
(Though I'm still amused that 0x12 is a valid variable name in emacs lisp!)

After seeing yet another YAML dialect for controlling systems, I think we need a hierarchy of YAML dialect expressiveness.
(1) Has its own variable binding system.
(2) Supports if statements.
(3) Supports loops.
(4) Supports function definition.
2 seems to be the most common, but I've seen all of 1-3. Does level 4 exist in the wild yet?

I'm impressed by how many options I'm offered in Common Lisp (in this case sbcl on Sly) for a simple error like an invalid variable name!
