Comment on Gas-Golfing

Here is the gas-reduction report from gas-golfing session:
Comparison between commit fe5e0fc and 87b15f7

Conclusion

I average this is a -0.3% of gas consumption. This is good, but this comes at the expense of code smoothness. Does it makes sense to keep these changes @naddison36?

Gas Optimization Reduction Summary

Overview

This report compares Initial vs Final gas costs across various swap operations. All values represent reductions (negative numbers indicate cost decreases).

Summary Statistics

• Average Reduction per Operation: -2,236 units
• Average Percentage Reduction: -1.43%
• Largest Single Reduction: -4,418 units (WEETH_WSTETH operations)
• Smallest Single Reduction: -436 units (Bypass Router: EETH_WETH)

Note:

• Reduction on tests Bypass Router correspond to reduction obtained thanks to increasing optimizor_runs from 200 to 50000
