"Simple things should be simple, complex things should be possible." -Alan Kay

I'd like to simplify the syntax of function pre- and post-conditions when the contract block consists of a single assert statement. A special syntax for this special case would omit all of the following:
1) the block's curly braces
2) the assert keyword
3) the semi-colon ending the assert statement
4) the body keyword (if and only if it follows right after the block)

So, instead of writing this:

int func(int i)
in
{
    assert(i < 5);
}
out(r)
{
    assert(r < 9);
}
body
{
    return i * 2;
}

...you'd be able to write this:

int func(int i)
in (i < 5)
out(r) (r < 9)
{
    return i * 2;
}
