Can I use AssemblyScript?

Hi team,

Do you see any issue with using https://www.assemblyscript.org/ ?

I tried to compile your simple accept hook with AssemblyScript but when I submit the transaction with ripple-lib I get an error message:

data: {
    resultCode: 'temMALFORMED',
    resultMessage: 'Malformed transaction.',
    engine_result: 'temMALFORMED',
    engine_result_code: -299,

Also in the rippled logs are showing:

Thank you
