Hah, good point. I should probably just have just used ::class anyway 
(in which case the leading backslash is the quickest way of the sample 
code being pasteable into some other file):

if ( class_exists(\WeakMap::class) ) {

There's probably a bunch of other style no-noes in that example, but I 
did at least test it worked. :)
