Understand. Objective-C and Python also suffers from the 
arbitrary "@" syntax. Basically what I would like to see is 
"@keyword" on stuff that can be hidden without making the 
semantics less clear (so you could have a "hide/show" button in 
your editor). I think it also would make the language easier for 
newbies if they can easily separate 
advanced-stuff-I-don't-need-to-understand-yet from more vital 
constructs.

It is easy to come up with many potentially useful "compiler 
hints" for programmers that care about performance:

// allocate simd-aligned and 0-padded string by sacrificing 
memory for efficiency,
// if supported

@simd string

// force loop-unrolling modulo 4 in order to trigger SIMD 
optimizations

@unroll(4) for(…) {}

etc...
