Can't access word 'constructor' on lexicon

[JustenRickert]

The way you store words on the lexicon instance makes the word constructor impossible to store in the lexicon, and results in errors when trying to access it using en-pos

> const lexicon = require('en-lexicon')
undefined
> lexicon.lexicon.lactate
'NN|VB'
> lexicon.lexicon.beauty
'NN'
> lexicon.lexicon.constructor
[Function: Object]
>

When tagging...

> const pos = require('en-pos')
coundefined
> const { Tag } = pos
undefined
> new Tag(['constructor']).initial()
TypeError: entry.split is not a function
