Polyfill.io Name resolution pseudocode
// Functional Helper: When lambda returns an array, compose concat and map to return a flattened result.
// See https://gist.github.com/samgiles/762ee337dff48623e729 for an example
Array.prototype.flatMap = function(lambda) {
return Array.prototype.concat.apply([], this.map(lambda));
};
// Mock, imagine this is some function that maps a modernizr test name to the polyfill.io nomenclature, if it doesn't map,
// it must return the name as is. Must always be an array.

Get the current Python path as a string with correct path separator
import sys
import os
def pythonpath():
# Remove filter if you don't care about cases such as: ':/path::', where members of the path are
# empty. It would be slightly faster to complete this operation if the filter was not run but the size of the
# input is likely to be small
os.pathsep.join(filter(lambda path: len(path) > 0, sys.path))

Steps to reproduce JIT memory errors
make wlvlang-jit PYPYPATH=~path/to/pypy
# This should pass
make test_all_jit
# Unfortunately the path to the script needs to be relative! (I should fix that)

# This should cause a segfault or:
