+F.try().or()
+----
+
+Masala is a low level library. It's up to you to mix these functions. It's very common for some kind
+of job to mix `F.try(x).or(F.try(y)).or(z)`
+
+A useful snippet is this `tryAll` function
+
+```javascript
+function tryAll(array){
+ if (array.length === 0){
+ return F.nop();
+ }
+ let parser = F.try(array[0]);
+ for (let i=1; i < array.length; i++){
+ parser = parser.or(F.try(array[i]));
+ }
+
+ return parser;
+}
+```
