[−] Expand description

quote!(..) accepts arbitrary tokens and expands into a TokenStream describing the input. For example, quote!(a + b) will produce a expression, that, when evaluated, constructs the TokenStream [Word("a"), Op('+', Alone), Word("b")].

Unquoting is done with $, and works by taking the single next ident as the unquoted term. To quote $ itself, use $$.
