Non-int untyped numeric literal

[tv42]

Go constants are larger than int ("Represent integer constants with at least 256 bits." https://go.dev/ref/spec#Constants). If you try to use .Lit with even int64, jennifer makes it a typed constant.

Maybe .Lit should support math/big, and just insert the stringification as literal value -- those non-builtin types can never be typed constants, so there's no other possible interpretation.

Maybe if the caller wants a conversion, the caller should ask for a conversion..

I don't think this is a huge problem in real-world usage... Probably not big enough to further complicate the library. If you really need to emit a numeric const that overflows int, you could kludge it with Id - something like:

jen.Const().Id("BigNumber").Op("=").Id("100000000000000000000000")
