x operator on a list you can now say my @arr = qw(x y z) x 4

THAT ONE IS DANGEROUS! The current x operator provides scalar context to both its operands (@a = (1,2,3,3,3,3); print @a x 3; ==> 666), the new one will not. While this may seem unimportant since it's unlikely that you'd want to repeat several times the lenght of an array it may easily cause problems with things like foo(...) x 8. Suddenly the foo() will be evaluated in a different context! That might easily lead to hard to find bugs!

Update: Looks like the change is more restricted than I thought so it should not be a problem. Thanks Somni!

    [LanX]: before digging into deep debugging ... I have a strange UTF8 problem, probably it rings a bell:
    [LanX]: two utf8 strings from different sources are base64 encoded, but after joining both the umlauts in teh second get deleted
    [Corion]: LanX: You can't just join two base64 strings together
    [LanX]: (not a high priority bug because I can use some HTML entities in the second string)
    [Corion]: base64 is padded to a multiple of 4 chars (or something)
    [LanX]: misunderstanding, I joined them before converting to base64
    [Corion]: Also, I would be wary of encodings and try to make really sure that both input strings are UTF-8. Maybe join the input strings from one source together to see whether they decode as bad or not
    [Corion]: LanX: Then the problem should persist without encoding to base64 too ;)
    [LanX]: I think it's a flag problem ... I'll produce a reprodocable example for SOPW
