I'm starting to gain a better understanding of your point. But just remember this: According to the "Gory details of parsing quoted constructs", the following steps take place:

  1. Finding the end. (Compiletime)
  2. Removal of backslashes before delimiters. (Compiletime)
  3. Interpolation. (Compiletime)
  4. Interpolation of Regular Expressions. (Runtime)
  5. Optimization of RE Code (Runtime)

My question is how would you suggest /e be implemented: Before step 3, or after it? I don't know the answer to this, and I'm not sure what the ramifications would be. Currently the quoted version of eval interpolates variables in step 3, and that's why you sometimes have to escape variable names to delay their evaluation until execution time. It seems that it's destined to be a convoluted road to travel.
