CAS: Can't use "Minutes" with other Time Units

[Snorre]

Can't the parser be rewritten so that "min" in unit context does something different than if used as a function?
I'm just asking because units are enclosed in parentheses (at least if composite) preceded by an underscore which is preceded by a number.
On the other hand, function "min" can't occur in this way or am I missing something out?
Is there a way to define a function "1_" so that 1_(min) would be a functional call?
