This is a side-effect of the way WolframAlpha returns results. We currently 
just use the exact text of the last result (whether the result is from Google 
or Wolfram) when expanding the "@" variable. You'd get the same problem if you 
manually typed in something like that without using the "@" variable.

Since Wolfram often returns things like "0.069 kg (kilograms)", which is 
another way of writing "0.069 kg^2", and since WolframAlpha does not recognise 
its own answer syntax, people are getting bad results unless they manually 
remove the parenthesised portion. Strongly interferes with use of the "@" 
variable. Also interferes with new calculations when people insert a prior 
result by clicking one of the results in the scrollback buffer.
