def recursiveFormat(args, **kwargs):
    """
    Recursively apply `string.format()` to all strings in a data structure.

    This is intended to be used on a data structure that may contain
    format strings just before it is passed to `json.dump()` or `dumps()`.
    
    Ideally, I'd like to build this into a subclass of `json.JsonEncoder`,
    but it's tricky to separate out string handling in that class.  I'll
    continue to think about it.

# From Stack Overflow question:
# https://stackoverflow.com/questions/26216563/how-to-do-encapsulation-in-python
#
# Python has simple encapsulation, but it doesn't strictly enforce access to
# protected or private class members.  This is one person's attempt to
# address that in a (misleadingly named) class.
#
# Could this be done with introspection rather than using on `self.privates` and 
# `self.protected`? Follow the common Python style of naming variables `__a` and `_b`.
# Then the methods would check whether the names begin with `__` or `_` to allow or

jq: JSONL → TSV conversion

What is TSV?

TSV means "tab-separated values". I prefer this format over CSV ("comma-separated values") because it doesn't require as much quoting. Many programs that can use CSV formatted data can also use TSV, although they may need to be explicitly told of the different format if it's not detected automatically.

However, in any of the jq scripts below, "@tsv" can usually be replaced with "@csv" to get CSV output instead.
