Hi Joe,
The T appears to act as a function in your first option. Does that act like
"If true return the cdr then break out of the for loop"?
Yes, exactly. The 'T' is indeed not a function, but the marker of special
clauses in the 'for' syntax (but also 'loop' or 'do'). 'NIL' is also supported.
The reference of 'for' says, terse as usually:
If a clause has NIL or T as its CAR, the clause's second element is evaluated
as a condition and - if the result is NIL or non-NIL, respectively - the prg
is executed and the result returned.
I could do this in perl, but I wouldn't be building character ;-)
Yess :)
