My ideal would be to simply not allow having my_variable and myVariable in the same namespace but given that you can do that in essentially every language I sort of prefer that they have to refer to the same thing.
The benefit is to avoid confusing variables or procs named my_var, myVar and myvar.
var my_var = 1
myVar += 1
echo(my_var)
Will happily compile and give you 2. I'd prefer an error in that case because while I'm not liable to make that mistake but I could easily mistype long_variable_name as long_variablename without noticing and then cause myself problems when I try to grep. nim --styleCheck:error c x
This enforces the same capitalization style in your code: x.nim(1, 5) Error: 'my_var' should be: 'myVar'You cane enable styleCheck:usages by default in the compiler. Also, most editors do variable/proc autocompletion.
Also you can use nimgrep if have to search across projects written by different people.
Just to stress myself as an anecdote though, I have years in the language and it hasn't come up yet for me, and I've never needed to use `nimgrep`.
