Common Lisp is a compiled language that offers such capabilities
for dynamically scoped variables (via SYMBOL-VALUE) and for
instance variables (via SLOT-VALUE).  Retaining the symbol
information costs some space but not, in itself, speed.  I grant,
though, that producing a complete, high-quality Common Lisp
implementation is not "simple."
