Just run a query over the entire blockchain, looking at script opcode
use. I counted the number of times each opcode was used, in total:

I'm interested to see what scripts were using OP_DEPTH and
OP_CODESEPARATOR, as the latter appears to be useless to my eyes.

Could you give some tx ids which use unusual opcodes?

The OP_DEPTH are all screwups in P2Pool blocks.

( the software was making tiny payments to scriptpubkey 'script' due
to a bug, and it went unnoticed for a long time because it was assumed
that it was just some p2sh user intentionally being stupid )
