Any plans for Array support in Shaders?

[Wavertron]

I've been playing around with the Custom Pipleline/Shader code, similar to http://labs.phaser.io/view.html?src=src\renderer\Custom Pipeline.js

I wanted to start using some Arrays, but alas, it doesn't allow it right now, throwing console errors below:
 

ERROR: 0:14: '[]' : array constructor supported in GLSL ES 3.00 and above only
ERROR: 0:14: '[]' : first-class arrays (array initializer) supported in GLSL ES 3.00 and above only
ERROR: 0:14: '=' : Invalid operation for arrays

Are there any plans to add Array support in the Shader code, both manipulating them in the shader code and passing them in as uniforms?
