Hi @achille-roussel,

After investigation, I found that that panic is happening because the substituteTypeArgs function in the types.go file is not handling the case for *ast.IndexListExpr properly.

To fix this issue, we need to add a case for *ast.IndexListExpr in the substituteTypeArgs function.
