But this implies that internally Calc must interpret "7" as if it
was "7 one". Only then can one convert "7" to other dimensionless
units such as the "e T nm^2 / hbar" that appeared in my original bug
report. 

Currently the latter unit conversion does require the superfluous
step that one tells Calc in one or the other way that "7" means "7 one".
I suggest that this superfluous step should not be required.
