/**
* This package doesn't yet contain public symbols. Refer to
* $(D_PSYMBOL tanya.conv) for basic formatting and conversion functionality.
* This module provides $(D_PSYMBOL format) function that can convert different
* data types to a $(D_PSYMBOL String) according to a specified format.
*
* Format string is a $(D_PSYMBOL string) which can contain placeholders for
* arguments. Placeholder marker is `{}`, i.e. all occurrences of `{}` are
* replaced by the arguments passed to $(D_PSYMBOL format). An argument will be
* first converted to a string, then inserted into the resulting string instead
* of the corresponding placeholder. The number of the placeholders and
* arguments must match. The placeholders are replaced with the arguments in
* the order arguments are passed to $(D_PSYMBOL format).
*
* To escape `{` or `}`, use `{{` and `}}` respectively. `{{` will be outputted
* as a single `{`, `}}` - as a single `}`.
*
* If a custom data type (like $(D_KEYWORD struct) or $(D_KEYWORD class))
* defines a `stringify()` function that is callable without arguments and
* returns a $(D_PSYMBOL String), this function is used to produce a string
* representation for the value. String conversions for the most built-in
* data types a also available.
*
* $(D_KEYWORD char), $(D_KEYWORD wchar) and $(D_KEYWORD dchar) ranges are
* outputted as plain strings (without any delimiters between their elements).
*
* All floating point numbers are handled as $(D_KEYWORD double)s.
*
* More advanced formatting is currently not implemented.
