Re: factor-group function
Nice. The factorization is of course the "slow" part, whereas the result juggling is almost irrelevant time-wise. I wouldn't try to improve on your implementation, but as a hind-sight, I probably would have used (map list unici (count unici fattori)) instead of (transpose (list unici (count unici fa...

Re: Why the fexpr's internal variable's name couldn't be sam
Isn't it just a normal effect of dynamic binding; that any assignment always affects the "inner-most" variable of the name. It's not special to fexprs, but you can confuse yourself quite easily with "normal" lambdas if/when a lambda body refers to a variable outside its scope. For example, if you ha...

Re: How to get return value of every spawn process iteration
You could do something like this (dotimes (i cpu-num) (spawn (last (push (sym (string "ret" i)) returns -1)) (println i))) That'd make returns be a list of the return symbols, letting you do (eval (returns k)) to obtain the return value of the k:th sub process. Or, you may want an association list, ...

Re: Why is the behavior of "trim" function so strange?
Technically, since neither "\xbb\xe1" nor "\xce\xaa\xca\xb2\xc3\xb4\xbb\xe1" are valid UTF-8 strings, the trim behaviour is conveniently undefined. It appears the trim function expands "\xbb" into a 2-byte code, and "\xe1" into a three byte code, making its output valid UTF-8. ("\xce\xaa", "\xca\xb2...

Re: shell-like scripting
The ! function waits for the command to complete, so without the outer fork , only one sub process at a time would be performed.

Re: shell-like scripting
As you know, one way to pass command return code is via ! and wait-pid , the former captures the return code of the invoked shell command, and the latter of a child (though the function return values need downshifting 8 bits to be the actual return code). I made the following toy example to experime...

Well, being or not being a macro is, I believe, some flag attached to the symbol, which is set by the "(macro ..)" term.
