Parsing just expressions

[PeppeL-G]

acorn.parse parses statements, but what if you got an expression you want to parse? Such as function(){}? Then acorn.parse('function(){}') complains, as expected, but it would be nice if one could write acorn.parseExpression('function(){}'). The workaround I'm using now is acorn.parse('(<theArbitraryExpression>)') to ensure the code is interpreted as an expression statement, but this complicates error messages, and it case <theArbitraryExpression> is 2)*(3, there would be no error!.

If it's not to much work, I would be glad if you could add acorn.parseExpression (a function that parses one expression) to the API.

Yes, this is a feature I've needed as well, at times. A pull request would be welcome. It'd be great if the interface also supports a way to enable/disable the check for whether the expression takes up the whole string (to easily allow finding the end of an expression, for example when parsing a templating language).

Good point.
