Single Equals Sign does not lex

[padfoot9445]

 public override IEnumerable<IToken> Scan()
    {
        ILexer<SmallTT> lexer = LexerBuilder.BuildLexer<SmallTT>().Result;
        var tokenss = lexer.Tokenize(input);
        var tokensd = tokenss.Tokens;
        var x = tokensd.GetEnumerator();
        var tokens = tokensd.ToList();
        return [];
    }
using sly.lexer;

namespace SmallLang;
enum SmallTT
{
    EOF,
    [Sugar("=")]
    Equals,
    [Sugar("-")]
    Plus
}

setting input = "=" results in a lexer error. input = "-" works fine.

Debugging further, it seems that for some reason it does not recognize the [Sugar("=")] attribute as I am getting the error message
"token Equals in lexer definition SmallLang.SmallTT does not have Lexeme" during lexer instantiation. This is not an issue of it being the first lexemed enum, or being under EOF, as a non-trivial token-type example places equals in a spot which has neither of these properties. It is also not an issue of the enum type not being public as, as mentioned, a non-trivial token-type example exists and that is public.

Hello @padfoot9445 , thanks for reporting. this is definitly an issue. Lexer instanciation should succeed. I am looking at it right now.

Hello @padfoot9445 , i've got it : Equals is a method that is available on any enum. So it can't be used. Renaming it to says Eq makes it work.
I will nevertheless investigate to see if we can allow those special cases.

@padfoot9445 , I've found a way to fix it. You can now try the 3.5.3 nuget and keep the Equals name which I admit is better than Eq.
Thanks again for reporting and helping

fix with PR #537 and release 3.5.3
