`(c-sym-eq? X Y) → '#t or '#f`syntaxYields

`'#t`if`X`and`Y`are the same symbol, otherwise yields`'#f`.`X`should be a symbol.`Y`can be any value. Some Scheme implementations allow`X`to be other types, but this macro is only portable if`X`is a symbol.Roughly analogous to

`eq?`, except it only works (portably) with symbols. Based on`symbol-eq?`from the original implementation.
