// OBSOLETE /* Parse a Chill expression from text in a string,
// OBSOLETE    and return the result as a  struct expression  pointer.
// OBSOLETE    That structure contains arithmetic operations in reverse polish,
// OBSOLETE    with constants represented by operations that are followed by special data.
// OBSOLETE    See expression.h for the details of the format.
// OBSOLETE    What is important here is that it can be built up sequentially
// OBSOLETE    during the process of parsing; the lower levels of the tree always
// OBSOLETE    come first in the result.
// OBSOLETE 
// OBSOLETE    Note that the language accepted by this parser is more liberal
// OBSOLETE    than the one accepted by an actual Chill compiler.  For example, the
// OBSOLETE    language rule that a simple name string can not be one of the reserved
// OBSOLETE    simple name strings is not enforced (e.g "case" is not treated as a
// OBSOLETE    reserved name).  Another example is that Chill is a strongly typed
// OBSOLETE    language, and certain expressions that violate the type constraints
// OBSOLETE    may still be evaluated if gdb can do so in a meaningful manner, while
// OBSOLETE    such expressions would be rejected by the compiler.  The reason for
// OBSOLETE    this more liberal behavior is the philosophy that the debugger
// OBSOLETE    is intended to be a tool that is used by the programmer when things
// OBSOLETE    go wrong, and as such, it should provide as few artificial barriers
// OBSOLETE    to it's use as possible.  If it can do something meaningful, even
// OBSOLETE    something that violates language contraints that are enforced by the
// OBSOLETE    compiler, it should do so without complaint.
