#pike __REAL_VERSION__
constant defined = __builtin.function_defined;
+
+//! Calls the given function with the @tt{args@} array plus the optional
+//! extra arguments as its arguments and returns the result.
+//!
+//! Most useful in conjunction with @ref{map@}, and particularly in combination
+//! with @ref{sscanf@} with @tt{"...%{...%}..."@} scan strings (which indeed
+//! was what it was invented for in the first place).
+//!
+//! @example
+//! class Product(string name, string version)
+//! {
+//! string _sprintf()
+//! {
+//! return sprintf("Product(%s/%s)", name, version);
+//! }
+//! }
+//! map(({ ({ "pike", "7.1.11" }),
+//! ({ "whitefish", "0.1" }) }),
+//! Function.splice_call, Product);
+//! ({ /* 2 elements */
+//! Product(pike/7.1.11),
+//! Product(whitefish/0.1)
+//! })
+//! @endexample
+//!
+//! @param args
+//! the first arguments the function @tt{f@} expects
+//! @param f
+//! the function to apply the arguments on
+//! @param extra
+//! optional extra arguments to send to @tt{f@}
+//! @returns
+//! whatever the supplied function @tt{f@} returns
+mixed splice_call(array args, function f, mixed|void ... extra)
+{
+ return f(@args, @extra);
