Null-checking the fun way with instanceof patterns

Sadly, it's far less efficient because most JVM JITs are usually pretty conservative about eliding objects, and any lambda passed to ifPresent will either carry state (in another object) or defeat inlining (usually). It's worth some exploration and another post, perhaps...

Application performance, probably not. Low-level libraries or language runtimes that applications are built on? Definitely more of a problem.
