In stbl: Stabilize Function Arguments

Coerce a list to a specific class

Description

Coerce a list to a specific class

Usage

.to_cls_from_list(
  x,
  to_cls_fn,
  to_class,
  ...,
  x_arg = caller_arg(x),
  call = caller_env(),
  x_class = object_type(x)
)

Arguments

x	The argument to stabilize.
to_cls_fn	⁠(function)⁠ The ⁠to_*()⁠ function to use for coercion.
to_class	⁠(length-1 character)⁠ The name of the class to coerce to.
...	Arguments passed to methods.
x_arg	⁠(length-1 character)⁠ An argument name for x. The automatic value will work in most cases, or pass it through from higher-level functions to make error messages clearer in unexported functions.
call	(environment) The execution environment to mention as the source of error messages.
x_class	⁠(length-1 character)⁠ The class name of x to use in error messages. Use this if you remove a special class from x before checking its coercion, but want the error message to match the original class.

Value

x coerced to the target class.
