6. #### def Try(body: (Context) ⇒ Context, handlers: List[(Global.Symbol, Global.icodes.TypeKind, (Context) ⇒ Context)], finalizer: Global.Tree, tree: Global.Tree): Context

   Generate exception handlers for the body.

   Generate exception handlers for the body. Body is evaluated with a context where all the handlers are active. Handlers are evaluated in the 'outer' context.

   It returns the resulting context, with the same active handlers as before the call. Use it like:

   `ctx.Try( ctx => { ctx.bb.emit(...) // protected block }, (ThrowableClass, ctx => { ctx.bb.emit(...); // exception handler }), (AnotherExceptionClass, ctx => {... } ))`

   The resulting structure will look something like

   outer: // this 'useless' jump will be removed later, // for now it separates the try body's blocks from previous // code since the try body needs its own exception handlers JUMP body

   body: [ try body ] JUMP normalExit

   catch[i]: [ handler[i] body ] JUMP normalExit

   catchAll: STORE exception [ finally body ] THROW exception

   normalExit: [ finally body ]

   each catch[i] will cover body. catchAll will cover both body and each catch[i] Additional finally copies are created on the emission of every RETURN in the try body and exception handlers.

   This could result in unreachable code which has to be cleaned up later, e.g. if the try and all the exception handlers always end in RETURN then there will be no "normal" flow out of the try/catch/finally. Later reachability analysis will remove unreacahble code.
