I'd leave it as it is.
The complication which I see is that the start value has to be specified twice, if you want to explicitly specify the increment.
[MATH lang=ENG]range(-2,1,-2+0.3)=mat(-2,-1.7,-1.4,-1.1,-0.8,-0.5,-0.2,0.1,0.4,0.7,10,1)[/MATH]
At least the representation is consistent with MathCad ranges, and also consistent with how one would write a range by hand. However, it took me quite some time when starting with SMath to find out that the range variables are missing and how to specify ranges. AFAIK, in Mathcad there is no function for ranges, just type ; and you get the placeholders.
Would be fine to have that in SMath as well. This would perhaps be impossible if ; is set as arg delimiter. Then a double dot .. would be an intuitive shortcut
