[m2t-dev] [MTL] Blocks and init sections

[Laurent Goubet <laurent.goubet@xxxxxxx>]

Hi Arjan,

I have trouble understanding the expected way to handle InitSections 
throughout MTL. The spec defines an "initSection" reference on the 
meta-type Block, yet those are never mentionned in the grammar save for 
ForBlocks and Templates.

From the meta-model described in the specifications, I would have 
expected init sections to be useable on all blocks (if, let, file, 
query, macro, ...). Were they really meant to be accessible on for and 
template only?

As a side note, what is the expected scope of these init sections? For 
example, can they be used in the declaration of the for's "iteration" 
expression or only in the body of the for block? Along the same line and 
regardless of the answer of the former, can the variables declared in 
the init section be used in the "each" expression of the for since that 
can be considered part of the body?

Regards.
