- Note
-
These functions are slotted for deprecation, but it is on hold pending superior type inference for tupling anonymous functions.

Attributes
Turns a function A => Option[B] into a PartialFunction[A, B].
Turns a function A => Option[B] into a PartialFunction[A, B].
'''Important note''': this transformation implies the original function may be called 2 or more times on each logical invocation, because the only way to supply an implementation of isDefinedAt is to call the function and examine the return value. See also scala.PartialFunction, method applyOrElse.
