each compile error

[ariesjia]

i use coffee to write tag file .

each="{ items of  array}"

is ok ,

each="{ keys, items of  array}"

it will compile error : Warning: unexpected , Used --force, continuing.

I also use coffee,
each ="{key,items in obj}" is wrong.
after reading the source code, I think it may be a good idea to compile the code in '{ }' by 'plainjs', because the code writen in '{}' is always treated as DSL of the riotjs, like 'angular filter'

This is related to #1090
the new compiler has generic support to avoid this issues. If the first character inside an expression is ^, the expression is not passed to any parser. This is some sort of type=none at expression level.
e.g.

each="{^ keys, items of  array}"

Maybe in a future version we can do that for ifand each automatically.

Edit: I'll close this issue now, feel free to open it if you consider it necessary.
