This is exactly what Nim does. If you try to define both my_var and myVar it will error out.

The benefit is to avoid confusing variables or procs named my_var, myVar and myvar.

[Symmetry]

If you define them both yes, but you're still free to use them both.

  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'

Searching has never been a problem for me in years of using Nim but there is `nimgrep` bundled for style insensitive search. Also I'm no RE wiz, but seems like RE might help if it came down it.

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`.

You can use --styleCheck:usages or a linter to ensure that the style is uniform.

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.
