My original goal was to allow the qc team to write

text :id, :pg_401, :name

So the arguments in theory should be symbols not strings, hence the need 
for some kind of to_s/#{} hackery

However, coming from a Java background, "s1" + "s2" is a performance 
(memory/speed) nightmare, so I shy away from S1 + S2 and try to use 
#{S1}S2 where possible.  Perhaps string + string isn't so bad in Ruby, 
but old habits die hard...
