Hi,

a.b(c)
the result of subexpression a and c both are arguments to function c (the
"this" pointer is a regular argument) and the evaluation order of arguments of
a function is undefined as per the standard. Particularly in the context of the layout
builders that's probably something worth mentioning in the documentation.
Yes, I was bitten by that, too. Particularily when using builders for a
grid, in which one passes column and row indices... you can't just
declare an "int32 row = 0" before invoking the builder and then
increment "row++" in the parameters. I've solved it by doing this in a
subroutine at the time. But definitely worth mentioning in the docs.
Best regards,
