Hi, Laurent,
Infix (operators) has higher precedence than prefix (function
evaluation), so the expression
if get in info? to-file elt 'type = 'file [print elt]
is actually treated by REBOL in the same order as if parenthesized as
if get (in (info? (to-file elt)) ('type = 'file)) [print elt]
that is, the IN is applied to the INFO? object, but the second
argument is the LOGICAL! value FALSE, which, as the error message
stated, is not a WORD! value.
Since you just want to exclude subdirectories from the list of
contents of the current directory, you could write
foreach elt read %. [if not dir? elt [print elt]]
instead.
