Cast/convert dictionary to array of variants

Question

{
 'a': true,
 'b': true,
 'c': false,
 'd': false
} 
 The code above should dynamically be converted to 
 {
 { 'a': true },
 { 'b': true },
 { 'c': false },
 { 'd': false }
} 
 
 is that possible? Thanks in advance

Oh, I just remembered there's a cleaner way to do this using a!update() (which can inject a new property into an existing dictionary or map), so no need to manually construct a JSON string to back-convert. See below: a!localVariables(
 local!originalDictionary: {
 'a': true,
 'b': true,
 'c': false,
 'd': false
 },
 
 local!keys: a!keys(local!originalDictionary),
 
 a!forEach(
 local!keys,
 
 a!update(
 data: a!map(),
 index: fv!item,
 value: property(local!originalDictionary, fv!item)
 )
 )
)

I guess it takes a little trickery to get the plaintext key name to be the key in a new dictionary, but if we (for instance) use JSON as an intermediary step, that'll pretty much do it for us... 
 a!localVariables(
 local!originalDictionary: {
 'a': true,
 'b': true,
 'c': false,
 'd': false
 },
 
 local!keys: a!keys(local!originalDictionary),
 
 a!forEach(
 local!keys,
 
 /* note: double quotes have to be handled carefully here */
 a!fromJson(
 "{""" & fv!item & """:" & property(local!originalDictionary, fv!item) & "}"
 )
 )
)

What's your use case? 
 Depending on the particulars, I expect you could probably utilize a!keys() to get the keys from the original dictionary, then iterate over that list, creating a set of new dictionaries each containing just one property from the original.
