Operators
Fol allows user defined operators. An operator is any combination of the following characters:
= + - * / > .
@ $ ~ & % < :
! ? ^ # ` \ _
The grammar uses the terminal OP to refer to operator symbols as defined here.
Brackets
Bracket punctuation is used in various parts of the grammar. An open bracket must always be paired with a close bracket. Here are type of brackets used in FOL:
| bracket | type | purpose |
|---|---|---|
{ } |
Curly brackets | Code blocks, Namespaces, Containers |
[ ] |
Square brackets | Type options, Container acces, Multithreading |
( ) |
Round brackets | Calculations, Comparisons, Argument passing |
< > |

The grammar uses the terminal BR to refer to operator symbols as defined here.
