#### Global Set
|
||||
[ GLOBAL ] is a shorthand for [ GLOBAL.SETS ]
|
||||
#### Set Definition
|
||||
Sets are defined with the set keyword followed by an equal sign and a set expression:
|
||||
```
|
||||
set SHORT_VOWELS = [ a, i, u ]
|
||||
```
|
||||
Lists of sets can be defined using a comma followed by whitespace syntax
|
||||
```
|
||||
set PLOSIVES = [ p, t, k ],
|
||||
FRICATIVES = [ f, s, x ],
|
||||
LABIALIZED_PLOSIVES = { PLOSIVES yield [ X concat ʷ ] }
