swift-syntax extension to infer types from expressions based on literal information.
Implemented as an extension of the ExprSyntaxProtocol.
The type inferred from literal information can be obtained from the inferredType property.

"item1": [
(1, 2.0, "3", true),

],
"item2": [],
"item3": [
(1, 2, "3", true)

// Get the type of expr from the `inferredType` property
