`"hello" returns "hello" instead of `hello #8

The parser doesn't currently support quotation marks as part of symbol syntax. Marking this as an "enhancement" and adding it to my todo list.

Looking into this further, it appears that the official K5 interpreter does not support this quoted symbol syntax:

 `"a long symbol"
ERROR: rank
 `"abc"
ERROR: rank

oK aims to be compatible with K5 wherever possible, so it looks like this syntax will not be implemented.

How about `$"hello"?

JohnEarnest commented 9 years ago

The behavior of $ has changed. Rather than accepting a prototype, as in K4, There are a series of special symbols which can be used as left arguments to perform various conversions:

  `$"foo"
ERROR: type

 `i$"foo bar"
102 111 111 32 98 97 114

 `c$97+!5
"abcde"

As far as I can tell there isn't an equivalent of your example which permits casting a string to a symbol.

Ok (heh), thanks. Looks like K5 is a step down from K2 in some ways which is unfortunate.
