Wow. That's some scary stuff there.
Yet, you can do the same sort of Stupid Language Tricks in Python and
Perl as well. (LISP macros also come to mind.) PHP isn't alone in this
regard. I think the problem in the article really hinges on the
inconsistencies in interpretation of string constants, etc.
'Variable variables' aren't pure evil; they just provide a level of
indirection that allows for fine-grained loss of control at runtime.
They're also nastier to debug. Any language that has an 'eval' function
or allows you to dynamically control the interpreter (or compiler) will
give you this.
