Claude Brisson reopened VELOCITY-666:
-------------------------------------


Is there any reason not to use #blockmacro instead of introducing a new character? Even Jarkko didn't  remember the syntax on the user list... Since 1.7 is not released yet, it's still time to change it.

> Inspired by VELOCITY-583 (BlockMacro support) I implemented the same functionality in a slightly different way.
> The new syntax is:
> #@yourMacroName($arg1 $arg2) any valid velocity AST here #end
> so basically the syntax is exactly the same as for normal macros except you put that @ prefix to the macro name. That tells Velocity that there's a macro AST body that should be passed to the actual macro.
> And in the macro you can refer to the passed body 0-N times. Like:
> #macro(yourMacroName $foo $bar)
>    $bodyContent
> #end
