Questions :
* are stream separators ";" "&" "|" in the "for" loop - operators
in the usual sence ( like "," ) or they are pure grammar ?
* is prototype of the subrotine more regexp then expression ?
to what extent it is a regexp ? where it is stored , can we inspect it
or even change .
* do we have have an axcess to the signature of the
subroutine if we have been passed only its reference .
that is , for exemple , can
process( @x , &step )
guess how many arguments &step expects ?
* how one can write function analogous to "for" loop that will be able to
handle multiple streams ?
* how one can call subroutine "in place"
sub (str $x , int $n ) {
$x ~ ["one, "two", ... , "hundreed"][$n]
} . ( "/home/temp/", $f ) ;
or
given ( "/home/temp/", $f )
-> ( str $x , int $n ) {
$x ~ ["one, "two", ... , "hundreed"][$n]
};
it seems that the last does not work because given take only one argument.
thanks ,
