Hi, 
> Are the dashes acceptable or undesirable?


I think without dashes it is more in line with other keywords, like 
"instanceof" or "insteadof". 

Because keywords are not case sensitive, one who likes them to be more readable 
could write them camelCased, for example "readOnly", or "writeOnly".
