query_to_expr_bare

Convert query definition to expression

Syntax for defining complex filtering expressions in a programmatic way.
A filtering query, built as a nested list configuration, can be easily stored in other formats like 'YAML' or 'JSON'.
What's more, it's possible to convert such configuration to a valid expression that can be applied to
popular 'dplyr' package operations.
