Compares 5 strategies for accessing integration points during assembly:
- OLD: Runtime dispatch + mutable struct with Dict (type-unstable)
- Option A: Compile-time function returning tuples
- Option B: Store in element as NTuple (current approach)
- Option C: Compile-time with Vec{D} from Tensors.jl
- Option D: Pre-computed global constants
- Option E: Function returning pre-computed constant
Validates that compile-time generation (Options C-E) matches the golden
standard architecture from nodal assembly demos. Includes realistic FEM
assembly comparison showing performance difference between old runtime
dispatch and new compile-time approach.
Recommendation: Option C (compile-time with Vec) or D/E (pre-computed)
for zero allocation and full inlining, matching eval_basis! pattern.
