Reproducing a naming collision with wagmi codegen

When using solmate's MockERC20 in a Uniswap v4 repo, wagmi codegen fails

This is caused by naming collision with Uniswap v4-core's MockERC20

If you manually modify the v4-core codebase MockERC20 -> UniMockERC20, wagmi codegen succeeds

Reproduce:

yarn install
forge build --force
yarn wagmi generate

Error:

yarn run v1.22.19
$ /Users/saucepoint/code/wagmi-uniswap-v4-bug/node_modules/.bin/wagmi generate
