I was looking at the YUI Compressor and came across this piece of code in the ECMA.NET project (Continuation file if you are interested).

protected internal override int FindPrototypeId (string s)     {         int id;         #region Generated PrototypeId Switch     L0: {             id = 0;             string X = null;             if (s.Length == 11) { X = 'constructor'; id = Id_constructor; }             if (X != null && X != s && !X.Equals (s))                 id = 0;         }     EL0:         #endregion         return id;     }

I have no idea what L0: and EL0: are doing here and have never seen this before. The term seems too rudimentary for google as well.

Anyone know anything about this?

  1. They look like lables for use as goto targets. See http://msdn.microsoft.com/en-us/library/13940fs2.aspx for more information.
