Ok, jumping into the deep end of the pool, potential semiotic [0] interpretations:
bug screen (Poisson) & computing grid (Fourier).
Permits one to crunch the numbers without eating the sprinkles. aka gets around the 'You can't have your cake and eat it'[1] issues.
symbolically supports the no formalism approach: a) Pi is irrational number. b)Raspberry is stand in for Bronx cheer [2][3].
Perhaps not being able to eat the cake & complete the project is a good idea (less sugar high & more realistic interpretations/results).
