Re: Re^2: Distinguishing a v-string from something else

Ahh, but I didn't say that v1.0 eq "1.0"; I said '1.0' eq 49.46.48, and they are:

>perl -MDevel::Peek=Dump -e "$a=49.46.48; $b='1.0'; Dump $a; Dump $b"
SV = PV(0x225484) at 0x19245fc
  REFCNT = 1
  FLAGS = (POK,pPOK)
  PV = 0x22ce4c "1.0"\0
  CUR = 3
  LEN = 4
SV = PV(0x2254b4) at 0x1924608
  REFCNT = 1
  FLAGS = (POK,pPOK)
  PV = 0x22b424 "1.0"\0
  CUR = 3
  LEN = 4

Oh, two BTWs: all strings are stored as an array of chars (c-style); base doesn't enter into it, in the same way as 0x10 and 16 are both the same number. It's just that Devel::Peek prints nonprintable characters as octal escapes.
