#14 Check for anything to do with arrays

[mcandre]

Arrays are bashisms, lol. Attempting to access a variable as somevar[@] (for-loop form), or somevar[*] (string joining form), represents bash syntax, whereas POSIX sh has not even an array type.

(I spoke too early in this comment about treating some things like for, $@, and $* as bashisms.)

[mcandre]

Note that the for keyword is NOT a bashism. The for loop has been in POSIX sh for some time, though it can only be used with an array literal or with $@ (implicit when the "in foo bar baz" part is omitted), not with any kind of array variable.

$@ is not a bashism.

$* is not a bashism.

${@:someinteger} and "${@:someinteger}" ARE bashisms, as bare POSIX sh does not features these shift shorthand convenience forms.
