in thread Numification of strings

"As you can see $a is a string "PV", while $b is an int "IV", even thought it was never used in an numeric context."

If you mean what I think you mean -- that $b is an int BECAUSE it was never used in a numeric content -- I think you're wrong, morgon: $b IS an IV, because it was instantiated that way... as an integer, without quotes that would have made it a string.

Update: Maybe I have the code tags right... at last.

    I meant to disprove the theory that a value becomes an int only after being used in a numeric context by showing an example in which a value is only instantiated (and never used in a numeric context), yet still is numeric.

    Or less convoluted: I probably meant what you said.
