Just as a note on naming - the namespace of SPL is already incredibly overloaded so the searchability will be quite poor. It's used (IMO misguidedly) by Splunk and has an older meaning in "System Programming Language" which used to be a pretty wide term to cover any architecture specific functionality activated by library from higher language (i.e. C) or directly through assembly. Granted, amusingly enough, for a language that specifically tries to account for the difficulty in naming variables, it is extremely fitting that the language is, itself, poorly named.
