Not the syntax but programming style. In general: no. Ada 2012 w/ aspects *can* (IIUC) be Eiffel-like, but SPARK goes beyond that into provability. [That surpasses mere precondition/postcondition checking.] IIRC, This thread has an interesting comparison: https://groups.google.com/forum/#!topic/comp.lang.ada/Wt1CnIb1kAE HOWEVER, having said that, there are some interesting results from a study on how contracts are used in Eiffel on SPARK's website: http://www.spark-2014.org/entries/detail/studies-of-contracts-in-practice
