Don't worry: targeting high-level languages gives you a different, equally-frustrating set of problems! Actually, many of them have equivalents to the low-level ones: you also have to worry about calling conventions, name mangling, runtimes… they just look quite different.

Especially you want to support any kind of dynamic functionality, there are many uncomfortable trade-offs involved.
