When extending the "[" method to a new S4 class, the default value for the drop
argument is not being found. Here is a small example:

setClass("test",representation(x="character"))
setMethod("[","test",function(x,i,j,...,drop=TRUE) {print(i);print(drop)})
a = new("test",x="fred")
a[1]

resulting in:

[1] 1
Error in print(drop) : argument "drop" is missing, with no default

I'm expecting TRUE for the value of drop. That's correct isn't?
