The back ticks to quote the keys are off-putting.. It feels like writing arcane SQL.

I personally would try and align with jsonpath for the convention, richer query-language and expressions.

Please, developers, don't use back ticks. They're not as accessible in other keyboard layouts.

I can use other symbol than back tick. But what symbol fits here better? what symbol would you use?

[ASalazarMX]

I'd prefer no quotes, but that would restrict the dictionary to keys without spaces. Maybe square brackets, since anyone using python already types those to access dictionary keys.

Yes, I wanted SQL like syntax and I'm happy it feels like this
