inline

Evaluate R(A0,A1,...) as a transform either with call<> or with make<> depending on whether is_callable<R>value is true or false.

Parameters

e	The current expression
s	The current state
d	An arbitrary data

Precondition

matches<Expr, Grammar>value is true

Returns

which()(e, s, d)

References template.
