Forgive them, Lord, as they don't know what they are doing

This is a matter of faith and compromises compromise it! The heretics

This is true but not-mathematics specific
I enjoyed this discussion. Basically I see no reasons beyond aesthetic
ones and "I do as my supervisor did"

At let me quote myself "All mathematicians understand and know
integral of cocycle over cycle. However some mathematicians still
remember very esoteric notion of \int_a^b f(x) dx" :-)
