Obviously some will find this a silly opinion but the one thing that turned me off the most about the Nim programming language was its use of significant whitespace. The same is true with F# (and of course Python). Having had apps with YAML for config, and having had nightmares trying to copy/paste config directives from various sources, I just find whitespace to be unwieldy. Now that's a strong opinion, (weakly held…
Never understood how putting up roadblocks for developers trying to copy-paste code was deemed acceptable, or GVR (and others) thought the solution to poorly formatted code was making formatting carry semantics instead of just writing an auto formatter.
Well of course that's completely ahistorical. The motivator was eliminating block terminators. Python's predecessor, ABC, was a teaching language; programs were small and refactoring was not a thing. Heck, copy-paste was hardly a thing, and there certainly were no auto formatters. Indented code was a step up from BASIC, the teaching language prevalent at the time.
