The verify Function in the Natural Units Environment

Description

 • In the Natural Units environment, the global verify function is replaced by a verify function that converts any unevaluated arithmetic operators, equalities, or inequalities to their global equivalents.  The first two arguments are tested to check whether they are valid unit names.

 ${\mathrm{true}}$ (3)
 > :-verify(m, 1250/381*ft, 'units');  # this returns false as 'm' is not interpreted as a meter
 ${\mathrm{false}}$ (4)
 > verify(m, 1250/381*ft, 'units');
 ${\mathrm{true}}$ (5)
