To be also able to build mruby without presym in the future. However, `MRB_QSYM` has been removed and changed as follows: ### Example | Type | Symbol | Previous Style | New Style | |---------------------------|--------|------------------|----------------| | Operator | & | MRB_QSYM(and) | MRB_OPSYM(and) | | Class Variable | @@foo | MRB_QSYM(00_foo) | MRB_CVSYM(foo) | | Instance Variable | @foo | MRB_QSYM(0_foo) | MRB_IVSYM(foo) | | Method with Bang | foo! | MRB_QSYM(foo_b) | MRB_SYM_B(foo) | | Method with Question mark | foo? | MRB_QSYM(foo_p) | MRB_SYM_Q(foo) | | Mmethod with Equal | foo= | MRB_QSYM(foo_e) | MRB_SYM_E(foo) | This change makes it possible to define, for example, `MRB_IVSYM(foo)` as `mrb_intern_lit(mrb, "@" "foo")`, which is useful if we support building without presym in the future.

* For `MRB_OPSYM`, specify the names corresponding to operators (refer to

|
|
* Other than that, describe only word characters excluding leading and
|
|
* ending punctuations.
|
|
*
|
|
* Example:
|
|
* MRB_OPSYM(and) //=> &
|
|
* MRB_CVSYM(foo) //=> @@foo
|
|
* MRB_IVSYM(foo) //=> @foo
|
|
* MRB_SYM_B(foo) //=> foo!
|
|
* MRB_SYM_Q(foo) //=> foo?
|
|
* MRB_SYM_E(foo) //=> foo=

* MRB_SYM(foo) //=> foo
