Re: Clarification on # as valid symbol character

x27;<' are in common use as part of symbol names. ('$' seems often used with as->). As a user, I see one description in text, but in real world code I see other things in use, and that makes it confusing. It would be useful (to me at least) to have this be a little clearer w

Re: Clarification on # as valid symbol character

Hi Ikuru, I'm afraid that section of the site doesn't really clear it up for me. There's a difference between when # is found as the initial character of the next item to read and when it's in the middle or end (i.e., auto-gensyms). (It's okay though; I'll reply further in my reply to Alex's

Clarification on # as valid symbol character

Hi All, I wanted to understand whether '#' may be treated as a valid character for symbols. The Clojure site [1] has: "Symbols begin with a non-numeric character and can contain alphanumeric characters and *, +, !, -, _, ', and ? (other characters may be allowed eventually)." I realized I was us

I'm not aware of anything that would lead to significant differences in regards to the function call. As a test, I defined an interface and used deftype and defrecord, then used no.disassemble[1] to inspect the results, using the following commands: user=> (use 'no.disassemble) user=> (defint

Yes, Pink is written mostly in Clojure, with two Java classes there. In terms of efficiency, Pink is slower than SC and Csound. I found it a little hard to benchmark, as the systems aren't quite apples to apples (e.g., SuperCollider use a 32-bit signal processing chain, while Csound and Pink use 6
