* Generify, needs some testing and review * Remove unnecessary change * Whoops, ? capture that type * Misread the docs, whoops * More permissible arithmetic operations * Implement believed Optimize generics * Missed a few generics * More permissible expr for arrays in parameters * More permissible expr for bitvecs in parameters * More permissible expr for bools in parameters * More permissible expr for fps in parameters * More permissible expr for fprms in parameters * More permissible expr for ints in parameters * More permissible expr for reals in parameters * Undo breaking name conflict due to type erasure; see notes * Whoops, fix typing of ReExpr * Sort corrections for Re, Seq * More permissible expr for regular expressions in parameters * Fix name conflict between sequences and regular expressions; see notes * Minor typo, big implications! * Make Constructor consistent, associate captured types with other unknown capture types for datatype consistency * More expressive; outputs of multiple datatype definitions are only known to be sort, not capture, and Constructor.of should make a capture * Be less dumb and just type it a little differently * Update examples, make sure to type Expr and FuncDecl sort returns * General fixups * Downgrade java version, make it only for the generic support, remove var and Expr[]::new construction * Turns out Java 8 hadn't figured out how to do stream generics yet. Didn't even show up in my IDE, weird
