And how do you propose to do string interpolation?

echo "This is a $var in a string";

or:

echo <<<EOB
This is a $var in a heredoc
EOB;

This is the heart and soul of PHP which isn't possible without a way to 
identify a variable.  I suppose you could argue that you would have two 
ways to indicate a variable, $var for interpolation and var without, but 
that gets even messier.  One consistent way is cleaner.
