Haskell compile time function calculation
- by egon
I would like to precalculate values for a function at compile-time.
Example (real function is more complex, didn't try compiling):
base = 10
mymodulus n = n `mod` base -- or substitute with a function that takes
-- too much to compute at runtime
printmodules 0 = [mymodulus 0]
printmodules z = (mymodulus z):(printmodules (z-1))
main = printmodules 64
I know that mymodulus n will be called only with n < 64 and I would like to precalculate mymodulus for n values of 0..64 at compile time. The reason is that mymodulus would be really expensive and will be reused multiple times.
