Both ExprTools and LLVM export "parameters"

[lcw]

With version 0.1.4 of ExprTools (see this commit) both ExprTools and LLVM export "parameters". This causes errors like the following when using CUDA.jl.

WARNING: both ExprTools and LLVM export "parameters"; uses of it in module CUDA must be qualified

Backports release coming in JuliaGPU/CUDA.jl#1027.

Awesome! Thanks once again for a quick response.

Just hit this too-- would be nice to declare incompatability between the offending versions in the registry to avoid this.
