Using an attribute with a hypen, followed by a alphanum character throws Antlr4.StringTemplate.Compiler.TemplateException #94
Description
The following throws Antlr4.StringTemplate.Compiler.TemplateException
new Template("{A-1}.Something", '{', '}');
The following does not:
new Template("{A-}.Something", '{', '}');
Ideally I'd like to use GUIDs, including those starting with numbers as an attribute but that may need a language spec change.
This is using "Antlr4.StringTemplate" C# package from nuget, version=4.0.6.9004 (running on Windows)
