There was a problem hiding this comment.
This is essentially Closure::fromCallable(), but this PHP 7.1 feature doesn't exist in HHVM yet, see facebook/hhvm#7874

This pull request implements the base64 output stream in userland on HHVM, working around facebook/hhvm#7659. See xp-framework/core#176
I first went down the way of implementing a php_user_filter class and exchanging the stream filter with this implementation, however, its
filter()method doesn't get invoked for the last chunk when the stream is closing due to facebook/hhvm#7889 - we need this to add potentially necessary padding.
