Strings are enclosed in double quotes ("), but is not a data type in Erlang. Instead a string "hello" is shorthand for the list [$h,$e,$l,$l,$o], that is [104,101,108,108,111].
($y gives you the ordinal value of the letter y)
I guess that's kinda fun. I'm starting to get feelings about Erlang similar to C++ -- it's somewhat perverse, but in a way I can appreciate.
filename foo.erl needs "-module(foo)" at the top of it, which is annoyingly redundant. although i wonder what happens when the two differ? could this be useful somehow? (nope, otherwise it will break code loading. well that's pointless)
The "-export" list which says which functions in a module get publicly exported, is redundant. I feel like I'm writing C header files again.
(that's hyperbole, somewhat)
Looking for the same function name but with a different number of arguments seems a little annoying. It would be a little more obvious to just give them different names. This may just be a deficiency in the coding style of the tutorial I am reading.
not really very useful for me, but i always thought it was a cool idea when i heard of it in smalltalk (i think). base#value where base is 2-36
(speaking of base 36... so that's what those dang reddit and youtube ids are!)
fun to have it; a refreshing change from python
% silently does nothing forever foo() -> foo().
# raises recursion limit error def foo(): foo()
