I don't think there are any other "functions" like this.
What about list(), isset(), print(), echo(), require(), include(), unset(),
empty()? We use them the same way as functions, but those are not real
functions.
All of them require to be followed by an expression (or some other
non-empty token), thus they do not act like constants the same way
'exit' and 'die' do:
- unset, isset, empty, list must be followed by '('.
- echo is a statement and needs to be terminated with ';'.
- print is an expression and requires a single non-empty expression.
- The include family is an expression and requires a single non-empty
expression.

PS: Today I learned that echo and print are not aliases.
