Description

Abigen fails for identifier named _100pct. I am guessing this has to do with the particular case of _ followed by a number. The transforming logic probably eliminates the _ and starts with whatever is next, in this case, the digit which becomes an invalid identifier. 10_0pct_ was the ident generated for _100pct.

I tried this code:

{
  "inputs": [],
  "name": "_100pct",
  "outputs": [
    {
      "internalType": "uint256",
      "name": "",
      "type": "uint256"
    }
  ],
  "stateMutability": "view",
  "type": "function"
},
