First, this would require using "fix" where it's not needed currently - breaking backward compatibility. Also what vid proposed allows to avoid fixes at all in all types of such definitions.

Second, it would cause even more problems with symbols like "forward" - if they were affected by "current level" of braces, you wouldn't be able to use the higher level "forward" for the contents of inner macro.

With the backlashes solution you just write "\forward", "\\forward" etc. for different levels.

Well, this approach is really good enough for everything. And even more, it improves the readability. Combined with preprocessor repetition and conditional preprocessing, it will simplify complex macroses a lot.

Will you include these in the next release? AND/OR the fasm documentation?

Yes, better solution. Backlashes provide an immediate visual indication of the level concerned.

Great, but there is only 1 question remaining to me:

Will this just remove all of the
Code:
_% %_ _local _common _forward _reverse    
crap we used to use a lot in fasm? You now, they will become pretty superfluous, because stuff like this:
Code:
macro SomeMacro
{

 macro Inner
 _%
  SomeStuff
 %_

 SomeStuff
}

_% fix {
%_ fix }
    


would become
Code:
macro SomeMacro
{

 macro Inner
 {
  SomeStuff
 /}

 SomeStuff
}

Yes, those fixes are already removed from the standard Win32 includes, replaced with the new solution.

I tried the example from the documentation but get "Error: unexpected characters." when assembling.

Code:
 rept 5 { in al,dx } 
    


It can be made to assemble with the addition of a variable name

Code:
 rept 5 v { in al,dx }

The code below causes FASM 1.61.7 to crash.

Code:
rept 1 {macro foo [arg] \{ \common nop \} }
foo test
    


The same thing, but with one extra line feed is okay.

Code:
rept 1 {macro foo [arg] \{
\common nop \} }
foo test
