Elixir
Oooh, so put_in, get_in and update_in are basically lenses. That's pretty cool
I don't like to rely on macros but it certainly is convenient
re: Elixir
@socks out of curiosity, what do you not like about macros?
-F
Serious reply, re: Elixir
@Felthry They make it very difficult to debug when something is wrong. It's not a problem at all when it's something built into the language's standard library and thoroughly well-tested but as soon as you step out of that, you're walking on thin ice
re: Serious reply, re: Elixir
@socks I'm guessing in this context it means something more complicated than how people typically use C preprocessor macros, then?
oh and assembler macros are hard to program without, i don't want to have to remember which memory location we stored this variable in and every location we referenced it in case we have to change it

re: Serious reply, re: Elixir
@Felthry Well yeah, that stuff is handled by language constructs themselves usually. By macros I basically mean code that is autogenerated at compile time
In Elixir they're used all over the place, and they're very convenient but I don't trust user-defined macros. In Haskell you see it in libraries like Persistent for example, where typing out the definition of a database table with Haskell functions is very tedious and you wanna automate it to some extent
