perleval({expr}) *perleval()*
Evaluate |perl| expression {expr} and return its result
converted to Vim data structures.
Numbers and strings are returned as they are (strings are
copied though).
Lists are represented as Vim |List| type.
Dictionaries are represented as Vim |Dictionary| type,
non-string keys result in error.
Note: If you want an array or hash, {expr} must return a
reference to it.
Example: >
:echo perleval('[1 .. 4]')
< [1, 2, 3, 4]
pow({x}, {y}) *pow()* pow({x}, {y}) *pow()*

{x} and {y} must evaluate to a |Float| or a |Number|. {x} and {y} must evaluate to a |Float| or a |Number|.
