Just note

instead repeated @external("debug", "...") you can simplified and grouped this to:

export declare namespace debug {
  function print32(value: i32): void;
  function print64(value: i64): void;
  function printMem(dataOffset: usize, length: i32): void;
  function printMemHex(dataOffset: usize, length: i32): void;
  ...
}

this behave and generate exactly the same as "atomic" external decorator.

But required call like this: debug.print32(0x80). So if this not what you want leave this as is

Another option could be to move all of the debug functions to a file named debug.ts, and rexport its elements from lib/ethereum.ts. By default, the file name without extension is used as the import's module name. If debug.ts resides within lib/, it's not necessary to re-export its elements because standard library exports become globals by default.
