Summary: expose parsedExpression in ExpressionBinding
Initial Comment:
I would like to have access to the parsed OGNL
expression in an expression binding.
I wrote a ValidField-like component that introspects
the OGNL expression to determine validation metadata
(w/ jakarta commons attributes) about the bound
property. It would remove some performance overhead, if
I could reuse the parsed expression, instead of
re-parsing it.

Tapestry uses a utility class, OgnlUtils, to parse OGNL
expressions and cache the result.
Inside ExpressionBinding:
_parsedExpression = OgnlUtils.getParsedExpression
(_expression);
ExpressionBinding provides an expression property (type
String). You can then invoke OgnlUtils.getParsedExpression
() to get the *same* parsed expression used in the binding.
