in thread if else and not reachable coding style

I'd probably go this path myself (or the third example).

It really all depends on the conditions and the context the sub is used in.

More often than not though, I don't have subroutines that can return several values where "undefined" isn't a possibility. Usually that being the case, a bare return at the end becomes the trap.

[1nickt]: pryrt I am creating a Type to check valid user IDs, which must be a whole number greater than or equal to zero. I would like to disallow 1.0 but because of this behaviour, by the time it is checked by the constraint, it *is* an Int.
[LanX]: should this be considered? Re: Parsing .txt into arrays
[LanX]: and this Re^4: Hash user input
[pryrt]: LanX, I would vote "keep" if it were considered: it's not helpful, but it could be taken multiple ways, not all of which are offenseive...
[pryrt]: 1nickt: if you are checking for valid user IDs, then I wouldn't care about the difference between 1.0 and 1: I would take either as a valid representation of the integer user ID#1
[LanX]: and this Re^2: extract column data
