\DOC parse_as_prefix

\TYPE {parse_as_prefix : string -> unit}

\SYNOPSIS
Gives an identifier prefix status.

\DESCRIBE
Certain identifiers {c} have prefix status, meaning that combinations of the 
form {c f x} will be parsed as {c (f x)} rather than the usual {(c f) x}. The 
call {parse_as_prefix "c"} adds {c} to the list of such identifiers.

\FAILURE
Never fails, even if the string already has prefix status.

\SEEALSO
is_prefix, prefixes, unparse_as_prefix.
