Yeah, someone pointed that out to me in #phpnw right after I posted this.
@phpmpan
Assuming $foo is an instance of Exception, it would echo 'bar' then throw an
exception, in my original though process, however someone pointed out to me
that
some language constructs (such as echo) already allow a comma separated list of
arguments.
Although, in that case the comma is not immediately followed by a variable that
can be converted to string, so I don't think that's as good a demonstration of
the issue at hand as johannes example.
It could work if the statements were separated by say, a colon, but this is
probably over-complicating things for a simple convenience.

if ($foo)
echo 'bar', throw $foo;
What should be the meaning of this code?

This leads to too many conflicts. For instance what should this code do:
if (condition()) echo foo(), bar();
right now it prints the returned values from foo() and bar(). This can't be
easily distinguished from your syntax. There are other similar cases. Such
special case syntax also makes the language more complex with more special
cases to mind.

Description:
------------
Allow statements to be separated by commas in single line if statements (when
omitting the braces)
Test script:
---------------
if ( isset($_GET['take_me_there']) )
header('location: /you_are_here.php'), exit;
Expected result:
----------------
The client would be redirected to www.yoursite.com/you_are_here.php and the
script would terminate execution.
Actual result:
--------------
Parse error: syntax error, unexpected ',' in /opt/lampp/htdocs/test.php on line
2
