That's why I said "the real question is whether the style was created with thought"
In that case, I misunderstood whose thought you were referring to and had taken you mean the originator of the coding style rather than the one using it.
When there are defined standards and well-known semantics, I'd love to here about them.
The defined standard is documented in perlre and the well-known default semantics are those which are used in the absence of any modifiers. There are certainly times when the default semantics need to be changed, thus the standard includes modifiers such as /s to alter them, but this does not change my original point that it is generally better to stick with the default (no modifiers) semantics where possible and only invoke modified semantics when there is a need to do so.
