The spacebar is huge and under both thumbs, because you use it a lot. - is far away under one fourth finger or pinky, it's bad to type. Shifted letters are common.

Seems like it should be shift+space inserts a variable-split-token and different editors can display it as a - _ or caps of the next character as desired. Like tab characters being configurable as a number of spaces.

or just use Nim which is style-insensitive: case except for the first letter is ignored, as are underscores.
