-/// grammer syntax:
-///
-/// ... the grammer takes entries parsed from the instruction,
-/// and updates the instructions with values based on the type
-/// of entry. i.e. immd would require a immd in the next argument,
-/// and update the low 16bits of the instruction.
-///
-/// GRAMMER -> ENTRIES
-/// GRAMMER -> ε
-/// ENTRIES -> ENTRIES, ENTRY
-/// ENTRY   -> rd           // i.e. $at
-/// ENTRY   -> rs
-/// ENTRY   -> rt
-/// ENTRY   -> immd         // i.e. 0x80
-/// ENTRY   -> offset       // i.e. main (16bits)
-/// ENTRY   -> offest(base) // i.e. 4($sp)
-/// ENTRY   -> target       // i.e. main (28bits shifted)
-///
-/// // grammer entries are always defined onto themselves... meaning the
-/// // name of their type directly corresponds to the mips field in the
-/// // instruction
-///
-/// pseudo grammer syntax:
-///
-/// ... psuedo entries represents what values should be placed where
-/// in each of the pseudo instructions. psuedo grammer is extended such
-/// that hardcoded values can be returned. i.e. setting rt=$at
-///
-/// GRAMMER  -> ENTRIES
-/// GRAMMER  -> ε
-/// ENTREIS  -> ENTRIES, ENTRYSET
-/// ENTRYSET -> ENTRY | SET
-/// SET      -> ENTRY = <REGISTER>
-/// ENTRY    -> <GRAMMER: ENTRY> // i.e. any valid entry from grammer synax
-/// ENTRY    -> hi // high 16bits of <target> into <immd>
-/// ENTRY    -> lo // low 16bits of <target> into <immd>
