  The new SpEL compiler is intended to address this need. The 
  compiler will generate a real Java class on the fly during evaluation that embodies the
  expression behaviour and use that to achieve much faster expression
  evaluation. Due to the lack of typing around expressions the compiler
  uses information gathered during the interpreted evaluations of an
  expression when performing compilation. For example, it does not know the type
  
negative.code: `someArray[0].someProperty.someOtherProperty < 0.1`
  
  which involves array access, some property derefencing and numeric operations, the performance
  gain can be very noticeable. In an example micro benchmark run of 50000 iterations, it was
  taking 75ms to evaluate using only the interpreter and just 3ms using the compiled version
  of the expression.
