Vl-follow-hidexpr-error

Report an error while following a HID.

Signature

(vl-follow-hidexpr-error short ss &key (origx 'origx) (x 'x)) 
  → 
msg

Arguments

short — Brief description of the error.
    Guard (vl-msg-p short).

ss — Detailed context for the error.
    Guard (vl-scopestack-p ss).

origx — Original, full HID being resolved.
    Guard (vl-scopeexpr-p origx).

x — Current place in the HID.
    Guard (vl-hidexpr-p x).

Returns

msg — Type (vl-msg-p msg).

This is smart in a few ways: it distinguishes between ordinary identifiers and hierarchical identifiers in the error type, and avoids providing excessive context if we haven't gotten anywhere down into the HID yet.
