Setting numeric value according to symbol with cl-case

Setting numeric value according to symbol with cl-case

[Heime]

Is this a good way to set a numeric value to a variable depending
on a whether another variable was set to a particular symbol.  Have
been scrutinising the possibility of setting a value to the symbol
itself, but do not know how.

  (setq mbcomplt
	    (cl-case armg
              ('auto 0)
              ('icomplt-horz 1)
              ('icomplt-vert 2)
              ('ivy 3)
              ('vertico 4)
              ('helm 5)))

Is it a good way to set a variable based on some
other variable?

It's a good WAY to do it ...

Obviously, you should use `pcase` rather than `cl-case` since you
intuitively chose the `pcase` syntax for your patterns (for `cl-case`
they kind of work but don't really do what you think).
