Finally, pure functional rust.
Neat FP style. Pretty verbose though. Someone should invent a terser syntax so you don’t need to write do_two_things everywhere. It’s a common operation so maybe it could even be a single character.
If you know about rust you know it’s a programmable programming language, meaning that you can make macros. There could be a macro that would do that but 1. Macros is rust code to write rust code so they have the complexity of rust squared 2. I said to myself the only macros I will allow myself to use in this challenge is println and allow
Isn’t this basically how lisp works?
Yeah, semicolons are ugly anyway and they’d ruin the beautiful expression of your code.
On a more serious note, does rust suffer some of the same issues as JavaScript when it comes to omitting semicolons?
Do not expect to find anything like Javascript craziness on other languages. Or you’ll be severely disappointed.
There are plenty of languages with warts at least as bad as JavaScript’s. Bash, PHP, C, even relatively sane languages like Python still have huge issues like implicit variable declaration.
Nope. In Rust, a semicolon denotes a statement while a lack of semicolon is an expression so you can’t just omit them at will. This does lead to cool things though like if/else blocks being able to produce values if they end in an expression. But the expression type is checked so you’re less likely to make a mistake. You can see an example here: https://doc.rust-lang.org/rust-by-example/flow_control/if_else.html
In JavaScript I never skip semicolons because I’ve seen those subtle bugs.
