Right, but if we're using @ to denote array references when declaring new variables, then I feel that everywhere we're dealing with references we should also use @ to remain consistent; even though there's no functional point in including @ in function parameters, for example, new Sourcepawn 2 users will see function headers without @ for arrays and assume that they're passed by-value, since declaring new arrays without the @ means precisely that.

For proposal 4, if we include @ in function parameters for arrays, then although it's consistent and easier to read, it's extra work for the user writing the code. Since it's always pass-by-reference then we could always omit the @ in function parameters for arrays, but then it's syntactically inconsistent with array references everywhere else.

In summary: minor nitpicking about syntax.
