Spec: https://github.com/ethereum/EIPs/blob/fad1a1acab0a433970e47e0b73a4f8a28c220675/EIPS/eip-7928.md (2026-02-03)

"In Ethereum we strive for a lean and easy to implement protocol. With your experiences from implementing core BAL parts gained in this chat - when analyzing the EIP spec in @EIPs/EIPS/eip-7928.md would you see potential enhancements or changes to the spec itself, which would significantly reduce implementation effort on the one hand and have no or only litte downsides (if present, please name them) on the other side?"

Add Fully Qualified ESM Imports
-------------------------------

*****************************
In test and src folder
*****************************

RUN TESTS OFTEN (AFTER EACH LARGE OP)!!
EVENTUALLY IN-BETWEEN COMMITS!!
NO REGEX/REGEX EXTREMELY IMPORTANT (OTHERWISE FALSE REPLACEMENTS)!!

Tape -> Vitest Regex Expressions
--------------------------------

import * as tape from 'tape' // No regex
import { assert, describe, it } from 'vitest'

import type * as tape from 'tape' // No regex
import { assert, describe, it } from 'vitest'
