c# 11 raw string literals

per docs, these are valid and invalid cases starting with c# 11

// valid
x = $"""The point "{X}, {Y}" is {Math.Sqrt(X * X + Y * Y)} from the origin""";
x = $"""The point ""{X}, {Y}"" is {Math.Sqrt(X * X + Y * Y)} from the origin""";
x = $""""The point """{X}, {Y}""" is {Math.Sqrt(X * X + Y * Y)} from the origin"""";
x = $$"""The point {{{X}}, {{Y}}} is {{Math.Sqrt(X * X + Y * Y)}} from the origin""";

// invalid
x = $"The point "{X}, {Y}" is {Math.Sqrt(X * X + Y * Y)} from the origin";
x = $""The point ""{X}, {Y}"" is {Math.Sqrt(X * X + Y * Y)} from the origin"";
x = $"""The point """{X}, {Y}""" is {Math.Sqrt(X * X + Y * Y)} from the origin""";
x = $$"""The point {{X}, {{Y}}} is {{Math.Sqrt(X * X + Y * Y)}} from the origin""";

also take a look at ‘what’s new in c# 11’ series: https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-11#raw-string-literals

tree-sitter doesn’t handle valid cases.
