ArrayVar=SecondValue
ArrayVar=ThirdValue
+For multiple variables to expand in FOREACH:
+
+ HTML='''
+ {{{!FOREACH ArrayVar!ArrayVarSecond!ArrayVarThird}}}
+ {{{ArrayVar}}}
+ {{{ArrayVarSecond}}}
+ {{{ArrayVarThird}}}
+ {{{!ENDFOREACH}}}'''
+ ArrayVar=FirstVarOnce
+ ArrayVar=FirstVarTwice
+ ArrayVarSecond=SecondVarOnce
+ ArrayVarSecond=SecondVarTwice
+ ArrayVarThird=ThirdVarOnce
+ ArrayVarThird=ThirdVarTwice
+
Implemented nestable "IF" and "FOREACH" expressions in templates. In other
words, there can be `{{{!IF}}}` inside other IF/FOREACH blocks, and vice versa.
