 @cindex Spawn statement
 
-A @code{spawn} statement consists of keyword @code{spawn}, followed by a
-normal @emph{call} statement (@pxref{Ref.Stmt.Call}).  A @code{spawn}
-statement causes the runtime to construct a new task executing the called
-function.  The called function is referred to as the @dfn{entry function} for
-the spawned task, and its arguments are copied from the spawning task to the
-spawned task before the spawned task begins execution.
+A @code{spawn} statement consists of keyword @code{spawn}, followed by
+an optional literal string naming the new task and then a normal
+@emph{call} statement (@pxref{Ref.Stmt.Call}).  A @code{spawn}
+statement causes the runtime to construct a new task executing the
+called function with the given name.  The called function is referred
+to as the @dfn{entry function} for the spawned task, and its arguments
+are copied from the spawning task to the spawned task before the
+spawned task begins execution.  If no explicit name is present, the
+task is implicitly named with the string of the call statement.
 
 Functions taking alias-slot arguments, or returning non-nil values, cannot be
 spawned. Iterators cannot be spawned.
