Oh, and because I missed bwoebi@'s comment... That's exactly the kind of edge case I included "[citation needed]" in my reply for. :)
Taht said, we could resolve that ambiguity by requiring parenthesis for print with multiple args, but at that point you have an exeption to the grammar rule, and you're not longer bringing echo/orint in line with each other and any consistency benefit flies away.

True about the difference being slightly larger, but as far as the original question goes: Yes, we could allow print to accept multiple arguments.
For that matter we could make echo return a value. Neither is going to break anything[citation needed], and due to the way the compiler handles both statements, neither will perform worse (fun fact: the compiler turn both into ZEND_ECHO opcodes, just with a different extended_value which it doesn't even use).
Should we? It'd be a grammar change, so you'll need an RFC and a 2/3 vote in favor of it. Without a compelling reason, I doubt you'll get that.

Small example:
foo(print 1, 2);
^ is 2 a second argument to print or to foo?
That's ambiguous, hence we do not allow that.

OK, so the documentation is wrong too?
@dm: sure, but that doesn't mean print couldn't support multiple arguments does it?

`print` has a return value along with outputting and can be used as e.g. `return print json_encode(...);` while `echo` can not.

That's not the only difference, the return types also vary. "echo" is "void" while "print" returns "int".
