OK, so it seems the operators work (both .≥ and .≤), but the parse tree is
wrong if there's no whitespace between the digit and the dot:
`julia> a=[ 1 2 3 4 5 6 7];
julia> a[5.≥ a] # fails
julia> a[5.≤ a] # fails
julia> a[5 .≥ a] # works
julia> a[5 .≤ a] # works
julia> parse("5 .≤ a")
:(5 .≤ a) `Inconsistent - yes, but at least no wrong result is produced.
