I can s s a variable "m". Is it good to allow this? I mean = it's > good that meters is "m" as expected but if someone wants to use "m" as = a > variable in the same formula it necessarily gets ugly. Given the number of units, it seems difficult to disallow using the same = symbols as variables. Many innocent-looking single-letter names are = units: s, N, m, A, V, W, J, g, l, ... For instance, 'e' both has a value (2.7something) and is a unit = (electron charge). Variables in Calc include not only names having an assigned concrete = value, but also variables in the wider mathematical sense since Calc is = capable of some symbolic computing. Units of measurement just use the = same mechanism and are treated as any other variables in all computation = except for operations explicitly related to units such as 'u s'. A serious reform seems unlikely unless someone really is willing to do = the work. More realistic might be adding a way to tell Calc which = variables you want to have typeset as units, as this can vary from = person to person and time to time. > BTW, do you know (Bug#30231) why allowed characters in units are > restricted? No idea, but isn't it just the restriction of variable symbols in = general? Unless they already play some syntactic role I suppose we could = be more permissive. Currency symbols like =E2=82=AC, =C2=A5 and $ appear = to be of special interest, but $ already has a special meaning.
