# math-symbols

Named symbols for use in compute algebra systems. Symbol names are stored centrally such that copies are cheap and need little memory.

## Example

`use` `math_symbols``::``*``;`
`//` Define a number of symbols with variable name equal to symbol name
`symbols!``(`x`,` y`,` z`)``;`
`assert_eq!``(`x`.``name``(``)``,` `"`x`"``)``;`
`assert_eq!``(`y`.``name``(``)``,` `"`y`"``)``;`
`assert_eq!``(`z`.``name``(``)``,` `"`z`"``)``;`
`//` Symbols are identified by their names
`let` xx `=` `Symbol``::`new`(``"`x`"``)``;`
`assert_eq!``(`x`,` xx`)``;`
`//` Symbols are ordered by their creation time
`assert!``(`x `<` y`)``;`
