syntax-quote

`form (with ~ unquote and ~@ unquote-splicing)

Builds a form as data: a symbol naming a var the namespace sees (its own or a referred one) qualifies with the var's namespace, so the expansion reaches it from any namespace; a special form stays bare, while every other symbol qualifies even when it resolves to nothing, like the oracle: a core name spells clojure.core/name (one a (:refer-clojure ...) filter hides spells its own namespace instead), any other unresolved spelling the defining namespace, an alias head its namespace, a class head its fully qualified name. ~ inserts its form's value, and ~@ splices a sequence into the enclosing list, vector, map or set. Each x# binds one fresh gensym per expansion -- the same symbol at every occurrence within it, a new one across expansions. Outside a macro body the template evaluates where it is written. An unquote outside any syntax-quote is an error, as is a splice outside a sequence.
