/*

pattern:

() | like in RE
|

* ? like in glob
|
|
(#U) expect a numeric value of unit U (use substring to get canonical value)

subst: $1 ... $field
|

substring:
|
|
$1, $2, ...

variable:

$foo, ...

with curly braces:
|

${foo}, ...

input variable:

|
|
Caveat:
|
|
|
|
Wrong: FN=* { X=$FN } there is no variable called FN
|
|
Right: FN=* { X=$$ } yields the Fn field selected by FN
|
|
|
|
Wrong: VAL=(#R) { R=$VAL } yields literal value
|
|
Wrong: VAL=(#R) { R=$$ } yields literal value
|
|
Right: VAL=(#R) { R=$1 } yield canonicalized value
