lambda?

meh so with time you grow tired of writing enum functions, meh:

problem is how to fit this with the syntax

JASS:

function err takes nothing returns nothing
    call ForGroup(meh, call KillUnit(GetEnumUnit () ) )
endfunction

becomes:

JASS:

function err__1 takes nothing returns nothing
     call KillUnit(GetEnumUnit () )
endfunction

function err takes nothing returns nothing
    call ForGroup(meh, function err__1 )
endfunction

?
Possibly working like that with set and return

if you manage to invent something that would also work with functions with arguments (so they become function pointers instead of code, that would be awesome.

JASS:

globals
    unit B=CreateUnit(/* ... */)
endglobals

function A takes nothing returns nothing
local unit b=CreateUnit(/* ... */)
    call ForGroup(G, function KillUnit(B))
    call ForGroup(G, function KillUnit(b))
endfunction

becomes:

JASS:

globals
    unit B=CreateUnit(/* ... */)
unit ___jasshelper_argument_unit1
endglobals

function prototype_001 takes nothing returns nothing
   call KillUnit(___jasshelper_argument_unit1)
endfunction

function A takes nothing returns nothing
local unit b=CreateUnit(/* ... */)
    set ___jasshelper_argument_unit1=B
    call ForGroup(G, function prototype_001)
    set ___jasshelper_argument_unit1=b
    call ForGroup(G, function prototype_001)
endfunction

Not without optional requirements/code.
Oh, and spell olympics judging. :P

Fledermaus	Wouldn't that just kill 1 unit rather than doing something to all units in the group Deaod?

Strilanc	How about.... lambda. JASS: call ForGroup(meh, lambda call KillUnit(GetEnumUnit()) endlambda)

TriggerHappy	How about multiple arguments? JASS: function omgwtf takes nothing returns nothing //some shit call ForGroup(group, doshit1::doshit2::doshit3) endfunction Will probably need a better syntax.

Deaod	Fledermaus, thats the point. I personally have no need for writing code this short. Passing arguments to code vars, however is a different story.

I'd rather keep it for one liner functions.

Or maybe extend deaod's idea and go back to this idea:

Cheezeman	I'd really prefer the idea of pasing on parameters to a custom function rather than a native, like in that link you added. Maybe it's easier to manage using a global hashtable with the group's handle-id as parentkey, and the parameter 'number' as childkey? I have no idea how optimized or buggy this will be though...

Vexorian	It sounds slower than the function call, that's for sure. I could probably not be bullet -proof. Hmnn, did anybody ever try to nest two ForGroups using the same group (but different functions) ? I think wc3 allows it. Now that I think of it, it is not even possible, there is no GetEnumGroup() native.
