using sync.Pool about validator

[deankarn]

I will look into it, thanks!

it helps with parallel benchmarks a bit and slightly increases the non parallel ones, but it's negligible.

since this library is fully thread safe and I suspect will be used within a webserver or some other logic that will be parallelized this change will help with that.

so going forward with the change.

Awesome, here another advantage:

• less code -> less possible bugs

😄

[deankarn]

True,

ok v5.10 is now out, I had to drop support for go 1.2 for this change, but I think that's more than justified.

@joeybloggs yes! I think it is ok to drop support for Go 1.2.
Go 1.4.2 is the most stable version to date and it is the default one in Google App Engine, so...
