Convert function takes string instead of type for conversion to #1026

What's your issue about?

If you forget to add quotes to the type you want to convert to, Vyper will give an unhelpful error:

convert(some_int128, uint256)
# raises:
#    AttributeError: 'Name' object has no attribute 's'

How can it be fixed?

So, catching this error might work out to fix this issue, but I think the underlying issue is that the second argument (convertTo) is a string instead of a typename. This actually makes it a little more unintuitive to write conversions as you could misspell the name and not get visual feedback from your IDE (assuming you have syntax highlighting up)

I would suggest turning this into a VIP to modify the syntax of convert such that a valid typename is supplied as the second argument

Yes agree, moving to convert(a, int128) without quotes is the way to go.
