Re: [#list with more than 1 variable and a complex condition, like java's for loop?

Yeah that's about right.  My use case is a little different - here's an example of what I ended up with:

[#ftl]

[#macro splice list1 list2]
	[#local n = list1?size /]
	[#local m = list2?size /]
	[#local i = 0 /]
	[#local j = 0 /]
	[#local nextSortOrder = 1 /]
	[#list 0..(n + m) as dummy]
		[#if i < n]
			[#local currentSortOrder = list1[i] /]
			[#if currentSortOrder == nextSortOrder]
				[#nested "list1" currentSortOrder /]
				[#local i = i + 1 /]
			[#elseif j < m]
				[#local currentSortOrder = list2[j] /]
				[#nested "list2" currentSortOrder /]
			 	[#local j = j + 1 /]
			[/#if]	
			[#local nextSortOrder = nextSortOrder + 1 /]
		[#else]
			[#break /]
		[/#if]
	[/#list]
	[#list j..m - 1 as k]
		[#nested "list2" list2[k] /]
	[/#list]
[/#macro]

[@splice [1, 3, 5, 7, 9, 10], [2, 4, 6, 8, 11, 12]; type, val]
	[#if type == "list1"]
		First list: ${val}<br />
	[#elseif type == "list2"]
		Second list: ${val}<br />
	[/#if]
[/@]

IMO [#continue /], [#stopGracefully /], [#for], & [#while] are things worth looking at adding to the language.  But we can certainly get by fine without them, it is just extra code.  More important would be nested callbacks from a macro (this was discussed on this list at length a long time ago, http://osdir.com/ml/web.freemarker.user/2005-09/msg00018.html).  That is what I need here to get rid of the [#if with the string compare, we have this in a few places and it is dirty but it works.  If I could add one thing to FM, it would be that.

Thanks

[#assign i = 0]
[#assign j = 0]
[#list 0..1000000 as ignore]
  [#if !(i < n || j < m)]
    [#break]
  [/#if]
  ...
[/#list]
