\DOC dest_abs

\TYPE {dest_abs : term -> term * term}

\SYNOPSIS
Breaks apart an abstraction into abstracted variable and body.

\DESCRIBE
{dest_abs} is a term destructor for abstractions:
{dest_abs `\var. t`} returns {(`var`,`t`)}.

\FAILURE
Fails with {dest_abs} if term is not an abstraction.

\EXAMPLE
{
  # dest_abs `\x. x + 1`;;
  val it : term * term = (`x`, `x + 1`)
}
