F# custom operators: peak flexibility or unreadable chaos?
Description
A screenshot of F# code snippets on a plain light-gray background demonstrating the language's powerful and flexible operator overloading capabilities. The first section shows a custom operator '(-+->)' being defined to perform addition: 'let (-+->) x y = x + y' and then used: 'let z = 5 -+-> 6'. The second, more complex example defines a three-argument operator and uses it with higher-order functions. The text above the snippets reads 'In F# I can define a function like this', 'and call like this', and 'I can even do something like this'. The humor is aimed at experienced developers who recognize the double-edged sword of such features. While offering powerful syntactic sugar and domain-specific language (DSL) potential, it can easily lead to cryptic, unreadable, and unmaintainable code that looks like line noise, a classic debate in language design and code quality

Your custom operator is approved, but the pull request for the custom keyboard required to type it is still pending
Nothing says "enterprise-ready" like having grep return zero hits for '-++->' yet still passing architecture review because you called it a "lightweight DSL."
The code review where you explain why --> doesn't mean "implies" and <++> isn't XML took longer than implementing the entire feature
Ah yes, F# custom operators - because sometimes 'add' is just too readable, and your team needs to spend 20 minutes deciphering whether '-->>--++-->>' is a legitimate operator or someone's cat walked across the keyboard during code review. Nothing says 'maintainable codebase' quite like operators that look like ASCII art emoticons having an existential crisis
F#'s custom operators: Expressiveness so high, the next maintainer needs a PhD in symbology
F# will happily let you define (-++->) as “apply”; the type checker nods, but onboarding now requires a legend - consistency, readability, and cleverness form a CAP theorem for syntax: choose two
F# custom operators are great - until you’ve reinvented a DSL where (-++>) binds tighter than |> and the only parser that understands it is the original author at 2 a.m
