[perl #128758] Reduce with numeric ops does not numify things if only one arg is passed ([*] set(1,2,3))

[Sam S. via RT]

It looks like this bug hasn't been *completely* fixed:

    dd &infix:<+>( "2" );       # 2
    dd &infix:<*>( "2" );       # 2

    dd [*] "2";                 # 2
    dd [+] "2";                 # 2

    dd reduce &infix:<*>, "2";  # 2
    dd reduce &infix:<+>, "2";  # "2"

i.e. it doesn't work when using the + operator with the functional form of 
reduce, even though it works with other numeric operators and with the 
meta-operator form.
