Support creating assigned variable name based on another variable like ${${var}} = Keyword

[zastress]

Apparently, it is not possible do return values into nested variables in RF, for cases like:

${x${y}} =    Keyword
${x}[a] =    Keyword

These can be quite handy aswell while using FOR loops, to populate values inside, like:

FOR    ${INDEX}    IN RANGE    1    4
        Keyword1    ${user${INDEX}-email}    ${user${INDEX}-fullname}    gender=${INDEX}
        ${short-id-${INDEX}}    API - Get User ID    ${user${INDEX}-fullname}
END

This is true. Notice, though, that

${x ${y}} =    Keyword

and

${x}[a] =    Keyword

are totally different features and thus need separate issues. The former is about creating the name of the assigned variable dynamically and the latter is about setting an item to a list, a dictionary, or anything else that has __setitem__. Both would be useful, but their implementation is different and most likely the latter is easier. I also consider the latter more useful and thus more important.

The example in the description uses the ${x${y}} style so I guess we could consider this issue to be dedicated to that. The other enhancement then needs a separate issue. I can submit it myself.

The proposed

${x ${y}} =    Keyword

syntax is interesting because something like that isn't directly possible in Python. You can do it with setattr, but that doesn't really work on module level.

Until this functionality is implemented, you ought to be able to use the Set Local Variable keyword as a workaround:

${ret} =    Keyword
Set Local Variable    $x ${y}    ${ret}

The proposed

${x}[a] =    Keyword

syntax is the same as

x[a] = keyword()

in Python. For it the current workaround is using Collections keywords to add items to a dictionary or list, depending on the type of ${x}:

${ret} =    Keyword
Set To Dictionary    ${x}    a    ${ret}

New #4546 now covers the item assignment syntax ${x}[a] = Keyword. I added both of these issues initially to RF 6.1 milestone.
