Rendering code blocks properly from .md files

[mojoa]

@freethebit

My opinion on this: its ugly, I don’t use shortcodes for a reason, mix stuff that is not content to content. If I need to use shortcode, I do not use.

@kaushalmodi

I am in the same camp.

Could you elaborate a bit on this? Or provide a link to discussion on this topic?
I am very curious about the reasoning for not using shortcodes. Thanks!
