Why sizeof int is wrong, while sizeof(int) is right?
...n imagine why it didn't bother. With the language as it stands, a type specifier never appears "naked" in an expression, and so there is no need for rules to resolve whether that second * is part of the type or an arithmetic operator.
The existing grammar does already resolve the potential ambiguit...

function! ShowColourSchemeName()
try
echo g:colors_name

In your example, you have:
if (new BigInteger("1111000011110001", 2).toByteArray() == array)
When dealing with objects, == in java compares reference values. You're checking to see if the reference to the array returned by toByteArray() is the same a...
