Even aside from that, some of us don't like really long lines of code. Having to scroll horizontally in GUI editors sucks, and I do most of my coding in good-old 80-column terminal windows. So it's not uncommon for me to split up a long statement into multiple shorter lines, since whitespace has no syntactic significance.
If CRLF becomes a potential statement terminator, then breaking a single statement across multiple lines not only becomes a minefield of "will this be treated as one or multiple statements?", but the answer to that question may change depending on where in the statement the line breaks are inserted!
If implemented, this change would make a mockery of any claims that Perl 7 will just be "Perl 5 with different defaults", as well as any expectations that it could be used to run "clean" (by some definition) Perl 5 code without modification.
