Deprecating ${} is possible resolution. One concern is ${} is common in shell scripting languages.

This "bug" is best solved by deprecating the ${} interpolation syntax for non-expressions.

Description:
------------
Both ${var} and {$var} are supposed to work, but ${$var} raises syntax error.

Test script:
---------------
php > $str = 'abc';

php > echo "${str{1}}";
PHP Parse error:  syntax error, unexpected '{' in php shell code on line 1

php > echo "{$str{1}}";
b
