That's why I wrote "CALC-like expressions".
Clients may want to allow things beyond the narrow limits of the existing calc/calcout records.

Fun fact: same thing caused Siemens to create all names for OPC UA with an extra set of double quotes around every name part in the hierarchy. Since special characters need to be quoted inside field values in EPICS databases...
  field(INP, "@PLC1 ns=3;s=\"DB1\".\"struct\ 1\".\"element\ 2\"")

Title:
  Invalid charactor in field name

Status in EPICS Base:
  New

Bug description:
  When creating a group in QSRV, the allowed characters are too
  restrictive

  error:
  Error Group not created: Invalid charactor '-' (45) in field name "BI02-TimeRise" must be A-Z, a-z, 0-9, or '_'

  expected behaviour:
  pva structures should allow for a more liberal set of characters that just what is covered by \w regex metacharacter.
