In many languages you get such functionality for free, because their
parsers are written to accept:

    expression '[' expression ']'

Thus, any expression that evaluates to an array can have '[]'.
Javascript, Perl and C are just a few examples.

The PHP parser is different. It requires a variable to the left of
'['. Changing this is not as simple as changing one or two YACC
rules.
