There is (at least) one other "strict" solution to this, which already is
utilized throughout the image - a multiple arg block:
Something>>voltageCurrentTorqueIn: aBlock
| voltage current startingTorque |
voltage := ...
current := ...
startingTorque := ...
^aBlock valueWithArgumnts: {voltage. current. startingTorque}
and the call would be
something voltageCurrentTorqueIn:
[ :voltage :current :startingTorque |
do whatever with these values
]
