8. #### 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 => {... } ))`

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

   try-catch-finally blocks are actually simpler to emit in MSIL, because there is support for `finally` in bytecode.

   try-catch-finally blocks are actually simpler to emit in MSIL, because there is support for `finally` in bytecode.

   A try { .. } catch { .. } finally { .. } block is de-sugared into try { try { ..} catch { .. } } finally { .. }

   In ICode `finally` block is represented exactly the same as an exception handler, but with `NoSymbol` as the exception class. The covered blocks are all blocks of the `try { .. } catch { .. }`.

   Also, TryMsil does not enter any Finalizers into the `cleanups`, because the CLI takes care of running the finalizer when seeing a `leave` statement inside a try / catch.
