-- Defines a quasi-quoting parser for unit expressions. Writing, say,
-- @[si| m/s^2 |]@ produces @(Meter :/ (Second :^ sTwo))@. A larger
-- example is
--
-- > ke :: Energy
-- > ke = 5 % [si| N km |]  -- 5 Newton-kilometers
--
-- See `Data.Metrology.Parser` for more information about the syntax
-- of these unit expressions.
