The problem is identifying if this would be faster than recomputing
the return value.
I used memoizers for exp and log (the most called functions in some
code I wrote) and it made the original version feel like it was
driving in reverse.
That's only true because, in your specific context, those functions
were called often with the same input. In a program that rarely use
the same inputs, your memoizing functions will just waste time and
memory.
No, because I use interpolation.
That's way beyond the ability of a compiler to do automatically. The
compiler would have to understand that the pure function produces
continuous results.
