What about list(), isset(), print(), echo(), require(), include(),
unset(), empty()? We use them the same way as functions, but those
are not real functions.
list() (and array()) may look like functions but do not behave like
one as they affect the current scope by setting various variables.
isset()/empty()/unset() require to work with undefined variables and
have deeply ingrained behaviour within the engine, so making them
simple functions is not as much of a "trivial" change.
print, echo, include(_once) and require(_once) do not mandate their
"argument" to be passed within parenthethis, so making them functions
does not simplify the lexer/parser nor removes them as keywords.
Also I don't know the last time I've used those language constructs
"like a function".
Seeing this list, makes me wonder: what about eval() ?
