「語言的一個有趣特點是，某種語言中 70% 的內容，其實是由幾百個常用詞組成的，」莫納漢說。「但真正難以在短時間達成的，是聽懂別人回你什麼，因為他們會不時使用那些較少見的詞彙。」

The tradeoff is complexity. The microcode must be carefully arranged so that the instructions in delay slots are either useful setup for both paths, or at least harmless if the redirect fires. Not every case is as clean as RETF. When a PLA redirect interrupts an LCALL, the return address is already pushed onto the microcode call stack (yes, the 386 has a microcode call stack) -- the redirected code must account for this stale entry. When multiple protection tests overlap, or when a redirect fires during a delay slot of another jump, the control flow becomes hard to reason about. During the FPGA core implementation, protection delay slot interactions were consistently the most difficult bugs to track down.
