Research direction

Start at packages/less/src/less/tree/ruleset.js around line 238 and inspect how a large importRules array is processed when the import option multiple is used. Reproduce the stack overflow with imported files containing many mixins, variables, and CSS guards; done means the case no longer exceeds the call stack.
